Instead of having to do the detune thing in the piano roll, there should be some way to put a note in, then type what note you want to slide to. For example, I'm trying to slide from F to D# and it's too confusing to do it with the detune option. It's in numbers instead of notes and I don't know how to navigate that at all.
Noo not at all. You can learn how easy it is in this tut:
