Why not set it up it moves them to the new group and removes the old group the only way would be to make the new group as primary. But if you really want this mod to work in a different way than it has been coded then you have the option to get a one off version that a coder can recode it the way you need but you would need to pay for that and it won't be cheap. I use the pro version of this mod myself and have it set a way that it works, it just takes time to set it up and a lot of testing, but you can make it work the way you want if you just take the time to set up all the permissions and groups the right way
