This is difficult to explain, but basically, I saw a post about how to make multiple parts with equations determined within an assembly, and I used this to create a modular assembly (call it assembly1) with multiple parts that rely on a global variable within it.  Now, I want to put multiple instances of assembly1 inside a larger assembly (let's call it assembly2), but I want the global variable to be different each time.  Is there a way to do that without needing to set a bunch of configurations/versions of the file?  I am trying to design a tool to be used by my sales team, so I am trying to make it as simple as possible.
