streamer editing 3-5 hour recordings. 10GB mp4 files on average

I am a streamer and have several recordings ranging from 3-5hrs. 75% is dead time thats easily cut out with split and delete. the remaining 25% is dozens of short scene's that don't all share the same purpose.I'd like to group these scenes into different catagories, add notes to each scene individually and export them in batches (and some individually) to separate locations. Is there an efficient way to do this on Rush desktop?
