Adding a Landing to two different stair type runs?

[Pshupe]

I have a set of stairs which has needs to have a different run for the last run of stairs.  I have created two different stair types for the different riser height for the last run.  I have left the landing associated with the lower run, stair type.  The second stair type starts from that landing and goes up to the roof.  I want to join the top run, stair type, to the landing of the lower run because it shows the stringer on the edge of the landing.  How can I join the landing and have it cut out the stringer at the bottom of that top stair run?  See image attached.

Ideally it would be nice if I could make a U shape stair with the second run having a different riser height but I don't think that is possible?

Also I have tried modifying the support in that area and it will not allow me to change the support type and won't let me slice that one member or adjust the length. 

Please advise.  Thanks in advance.

That does not work.  Landings must be closed loops and you cannot edit the structure.

How did you join your example?

My goal is to create a stair that looks continuous and has a run, or separate stair, that has a different riser height.  So far I have not seen a way to do this.

You cannot modify the structure as you show because that is just the landing and must be a closed look.  How did you join your stair?

How is the landing not a closed loop?  Did you split the landing sketch line AND delete a segment?  I said Split segment, not Delete segment, meaning you split one line to three lines but they still connect.

This works,  Thank you.  It's a little cryptic.  You need to split, then not delete, finish the sketch, then select the stringer piece and are able to delete.

Still don't understand how you can create different riser heights in the same stair type, unless you are adjusting the "desired number of risers"?

Thanks again for the help.
