Pipe Fittings do not work with layer modifiers in DWG Export

[gabriel.r.o.abreu]

I have to develop DWF to approval in regional administration with Layer information, exporting DWG from Revit and then DWF to AutoCad, however when i set the DWG Configuration to export plumbing with modifiers the pipes work as expected but the pipe fittings do not.

In this case i'm separating by Phase, in the layer "TUBO MÁGICO". The layers need to be: "TUBO MÁGICOExisting" and "TUBO MÁGICONew Construction". 

Export Setup in Revit separating Fittings by PhaseFitting Block Layer in CADInternal Layer in CAD

 I know that the internal layers of the pipe fitting family are not changing with the modifiers, only the block of that pipe fitting. To export to DWF this doesn't help and i have to change the pipe fitting layer by phase manually.

Any ideas to how to make the pipe fittings work with the modifiers?

Have you tried with the attached mark option.

Yes. Doesn't work. 

I'm changing the internal layers to "0". Has improved visually, but isn't perfect yet.

Any fix for this? I am having the same issue.
