Hi marco - the different commands in a "command set" like that are a bit different kind of thing than options in the Options dialog.

Right now there isn't really a way to toggle between those, but I do plan on adding a mechanism in so that scripts could determine the current running command, and that would then allow for a toggle script to be created for that.

Some recent discussion on that kind of thing here:
