I'm drawing a lumber rack. It's basically a bunch of lumber and OSB sawed up and screwed together.

Lots of the parts are a sheet of OSB cut out. Side views are sort of pointless, except that the shop needs to know how thick the piece is.

Problem - I started with all these pieces 1/2" ply. Oops we don't have 1/2" ply, we have 3/8", change to that, hmm... we have a bunch of 1/2" OSB laying around, change back to 1/2" thick

I change all the parts, but discover that I've got a lot of annotations like "sidewall 0.375 plywood 2 req" on drawings, and those aren't getting auto updated.

Is there a way to drive those annotations from the drawing, so when I change the thickness I change the annotation?
