Lexi, welcome to the forum. No, I don't think BIAB has this feature, but it's good you asked here first. Unless someone else says it does have this, then I suggest you go to the BIAB Wishlist Forum well below this one, and post a request there. It does sound like a useful idea that would save time.

Jcland, before we consider if this is a bug, can you answer two questions please. What version and build of BIAB is yours, and do you have frozen tracks (the frozen tracks would not obey a key signature change). You might also consider starting a new thread for this, as some will not see it here who might be able to help.
