Ultimate S question - Help!
 

Vasst support is out for a few days, so I'm hoping someone knows the answer to my question.

How do I use Ultimate S to swap out project files? It can be done, I know, but I lost the email from support explaining how it's done. I received instructions from them ages ago, and must have deleted it.

I normally use Gearshift for this purpose, but I cannot rename the new files to match the numbering of the original. I believe I can use Ultimate S to swap out even if the file names don't match, but I'm fuzzy on this.

Help! This is pretty urgent.
