How do you deal with sheet metal gauge?

Probably a question for M. G. Martinez, if you are watching.

The design is a top-down assy where everything is referenced to sketches/planes at the top:

How do you deal with sheet metal gauge?

Including the thickness of sheetmetal might be needed in order to be able to mate or reference features or assemblies to one side or the other of a sheetmetal part.

However, the issue here is that in general terms, I think it is better practice to use gauge tables when making sheet metal parts. If you want to avoid mating or refering to surfaces within sub-assembly sheet metal components you have to include sketch lines at the top level to reflect the thickness of the sheet metal being used. This poses a problem because you can't lock your bend table thickness selection to a dimension on a sketch . So, if you change the metal gauge at the part level you have to remember to go back to the top level assy and change your sketch to match. This, I think, "breaks" a nice top-driven parametric design.

The way I see it, if you want to be fully top-down, you can't use bend tables.

Am I missing something?

Thanks,
