Every track must be individually selected, right-clicked to gain property access and then have it's flags set which isn't very cool. I'd really like to be able to multiple-select tracks and mass-set a Wendy flag on them all at once.

As far as I know, you can group-select tracks in Emplode and apply properties including Wendy flags.

It's theoretically possible that this is only a beta12 feature and that's why I can do it and you can't. If you really and truly can't do this in beta11, well then it's a FITNR.
