Any way to make the STV generation more 'git friendly'?

Currently, the way the STV code in studio works, even minor changes to the STV ends up generating significant diffs in the file from the previous version. Looks like it's mostly Ref= and ID= numbers changing with each minor change in the file.

I'll be honest, I have very little idea of the actual way the XML is built for this, or what those ID and REF values are for, when there are also unique Sym= properties for each widget, but I wonder if there's a way they can be more 'preserved' from version to version.
