I can't seem to find a way to import my custom render templates from previous versions (13 or 14) of Vegas Pro into Version 15. If I create a new custom template it appears in the C:\Users\Username\AppData\Roaming\Sony\Render Templates folder and Vegas 15 can use it. But if I move any of the previous templates into that folder they won't appear in Vegas 15.

I don't see any mention of an "import" tool. Has anyone done this?
