So the issue I have with these solutions is I'm trying to use this as a workaround for the way Inventor places Factory part files in Vault.
When you configure Vault and Factory together there is a hardcoded folder generated in Vault titled Factory Assets.
When using a Factory Layout (Factory Assembly) in Inventor you place factory Assets by selecting them from the asset browser. This browser is full of "published assets" which are nothing more than .ipt files that have been "published" to Factory library. They are converted into .faf files and contain some key information that Factory uses to include Factory Properties.
When you place a Factory Asset, it puts that .ipt into your assembly with the name of the asset followed by a series of letters and numbers to essentially make it unique.

When you check the Assembly into Vault, this asset is saved in the Factory Assets folder in Vault. Any .ipt that is ever used through factory goes into this folder. If it is removed it loses it Factory functionality. The problem is the folder becomes rather extensive quickly and I have no identifier for archiving old files. This is why I'm trying to figure out how to change the file name before they get checked into Vault. I still want the auto-generated file name but I just want to add the identifier in the front. This would give me the ability to know what I can remove from the Factory Assets folder in Vault.
