Is there a way to Tshirt size by squad and not just by idea?

[Bob]

We have development teams or squads that specialize in certain skills 

An idea will be scoped and will often need engineering resources from multiple squads

When we tshirt size, we need to do that per squad for that Idea

But we can only size for the idea, thus applying a size that is the same for each team that will contribute to that idea, which is not correct and messes up our capacity planning

I want to be able to size by team so for Idea X, its an XS for Squad A, a Medium for Squad B, and a Large for Squad C
