I have created a custom transformer that's linked by default. I decided at some point while I was making changes that one of the changes warranted creating a new "Version", so now I have a custom transformer that has version 1 and version 2.
I have since decided that I no longer need version 1 but there doesn't seem to be any way of deleting it as it's embedded inside the .fmx file along with version 2. If I could delete version 1 then I'd rename v2 -> v1.
I guess I could edit the .fmx file with a text editor and I'm normally ok with getting my hands dirty doing that but this situation seems a little too risky.
