I do plan to do this. I started out with this feature trying to make it so it would omit files ignored in the source in the destination as well. This ended up having a few complications that nullified it as a possible path.

After that I decided to take the quickest path to a working update. I needed to use that feature.

I'd like to go back and add the ability to use a path, , *, or regex. Perhaps in the next version.
