Toggle between swing and even eights

The Beta 2 version of the MuseScore-program has a feature, "Swing" in the "Text"-box to the left, and it is fine to make a swing-feeling in the playback of a score.
I miss, though, an opposite feature, it might be named "Even" to put in the score, when even eights is wanted. Sometimes a score contains both even and swing eights, and it would be fantastic to toggle between the two features.
I hope it can be done without too much trouble.

P.S. I'm really most impressed by the program - it is excellent, and it is getting better every day, thanks to some clever programmers!
