assemblys global variables lost in sheetmetall part

Hi!

I am trying to reference to my assemblys equations from a sheetmetall part that is in this assembly. see pic.

sadly the spacing in pattern doesnt let me to choose the global assembly variable. why? how to do this in a clever way?

when I created the stairs pattern, I could reference to the assemblys equations. but now when I need to create the cut pattern, it doesnt work...
