Oh ok, sorry! I'm trying to figure out something for you in Cubase but I think a nice little feature would be this>
when slicing audio, I think the sliced up parts should be given a new name automatically, so say the audio I recorded would be named (in this instance I have "Audio 11_29") let's say you slice it up, the sliced up version should become "Audio 11_29a" or something like that to differentiate between the first bit that way when it's categorized in the pool it would show up as a different audio file so it could be massively selected then deleted and such.
I hope this is what you're getting at anyways, I'm really sorry if it's not
and I would probably look silly too
