I have an assembly that has top-level equations affecting individual parts. When I re-name a part or send it through a pack and go where the SW names get changed, these equations need to manually updated with the new file names. Is there a way to change that?

Or failing that is there a way to change the equations to a text file that I can do remove and replace of text with?

I see this has been asked a few times, but none have been answered.
