Mating in top-level assembly

Hey all,

I keep coming up to an issue where I am working top-down and would like to create subasemblies/subweldments from my top level assembly.  Is there a way to use the "form new subassembly" and not lose all the mates I have established? For example, in the photo, the box and the two mounting plates are a part of one weldment, while the tube and the other set of plates are a part of another.  I would like to define the location of the mounting plates via the geometry on the second weldment. From what I know, the only way to keep this parametric relationship is to bring the second weldment into the first one and hide/exclude from BOM after mating (so essentially the second weldment is in the top level assembly twice).


I have also been playing around with the first assembly being "flexible." This allows me to make the mates that I need, but they don't trickle down to the lower levels.


Thanks in advance!
