When I am editing a sequence I have it play certain files for almost everything to keep it related to holidays such as Christmas or Halloween. Audio bumpers for example. When I add an audio bumper to the sequence, the menu where you are able to edit, rename, copy, move, disable/enable, and remove it would be nice to have a "Play" option so that you could play that individual part of the sequence. This would help when I'm wondering if that specific audio bumper is what I wanted. Since I have so many I forget which ones are which and being able to play that individual part of the sequence would be nice to quickly see if it was what I was looking for.
This could be helpful with many things such as trivia and being able to quickly see if it's the right trivia you want, or trailers, intermission and all those other parts of the sequence. Being able to quickly view what you just added instead of having to watch the whole sequence to get to that part would be nice.
