Multiple Email Layouts

We really need a way to save different email layouts for different purposes. Right now, I have to store text files with source code for the different email invitations I need for the two brands in our university, plus different learner groups and situations. It would save me tons of time if I could set up different email invitations right in BlueVolt and choose the one I want to send at the moment I'm ready to invite a new user or group of users.
