More than 1 rejection letter/email?

Content

Right now when I reject a candidate for a req it prompts the rejection reason and gives me the button to check whether I want to send a rejection letter to the candidate.  Now if I check that box, it sends the Candidate Rejection Email that is in the system.  Is there a way to choose between several different rejection emails? Rejection reasons are different and I have like three different ones I'd love to be able to choose from rather than the standard. The only way I've figured out how to do this is through the Email Templates section,
