A little explanation as to why it doesn't work this way currently: We considered doing this, but it gets hairy with the Havoc Selectfire. We don't want to auto switch on the Havoc, so we decided it was better to stay consistent with a hopup, instead of making it change per gun. Additionally, since the selectfire has already been out so long, it would probably cause a bunch of people to get frustrated and die if they've learned to always swap fire modes, since the behavior has changed suddenly. Ultimately, we decided it wasn't worth the inconsistencies and changing existing player behavior, but it's something we are still looking at and listening for feedback on!
