Tile Finish Wall forces me to use core layer. Preventing ideal joining conditions.

[mar_zan]

Context:

Residential Project.

For detail sections, I use callout views and prefer to have as little editing as possible. I also like to use material tags to identify the various parts of the wall. This is a workflow I feel makes good advantage of Revit's BIM capabilities.

In the project I'm working on, each bathroom has it's own unique tile or wainscotting etc that has varying heights. For this reason I decided to make separate wall types for finishes. 

The issue is that these finish wall types force me to have something in the core of the wall. And as a result, when I need to join the tile with the adjacent wall, the tile goes all the way to the subfloor. If only I could have no core to the wall, it would behave correctly!

It seems like it's fairly common to have finish layers separate. So for those that do this method and make details, how do you deal with this join issue? Is there a solution I'm not seeing?

Some of the solutions I came up with were. 

1. Make the Cementitious backer board part of the finish wall (make it core, and finish layers non-core). Then remove it from the main wall. This works, however, the main wall is also related to wall types and wall legends. By removing the Backerboard it makes this method feel inelegant. 
2. Sandwich the finish layers into the wall. I tried this. And with my project in particular it is a nightmare. I just have too many weird situations, and when I need to make design changes it is far too cumbersome to deal with. 
3. Meticulously fix it in 2D by using the Cut Profile tool. For obvious reasons I would like to avoid this. 

And Happy Friday!

Additionally, I'll add that when in comes to plan. If I need to hide non-core layers of walls. For example in a plan that only shows framing. The finish walls will not hide because at least one layer of it is in the Core of wall. I need to either create a filter to hide finish Wall Types (a feature I don't have access to in LT) or manually hide it. 😞

Yes! Exactly. How do you work such magic!?

Tile wall: move tile layer out of core.  

Floor: move subfloor to core.

Interesting. So I never considered this because as I understood core layers, they represent the core structure of something. (Cementitious Backer Board I don't see as the core structure of the floor.) I thought it might conflict with the floor when it joins with an exterior wall. However, seems it joins fine! So I suppose this is solution, thank you @ToanDN 

EDIT: I still think it would be more elegant if the finish type wall could not have core, thus allowing me to keep the core structure of the floor making sense.

You can argue it both ways. 

Use an example of a floor with joists, plywood subfloor, and whatever finish on top of it: I definitely consider the plywood subfloor as a core layer.  Core and Structure are not the same.  That's why you can only check one layer in core as Structure.  Construction wise, the common practice is laying wall bottom tracks or plates on the plywood subfloor, not through it and on the structural joists.
