How to bulk copy part of the title to a different tag

Hi, I have different mix versions of the same title track. For example if my track is called "Heaven" I would have "Heaven - Full Mix", "Heaven - Instrumental Mix" and so forth. I would like to bulk copy the version part like "full mix", "instrumental mix" etc and copy them to a tag called "Version".
How would i do that?
Thank you

with %title% and %dummy% - %version%
