Attach Top/Base of wall

Hi Guys , is there any chance I can find a node in any package that works as attach top/base for walls ?
I would really appreciate such a thing
or is there any way I can change the profile of a wall ,
Or if I can cut walls when they intersect floors
Something Like this

I would really appreciate any help

no, it is not supported :frowning: I wish there will be in the future.
