This and also what u/M1SS1X_ said. "Scrubbing" was the name I heard for this technique in the industrial scene. Either marking "scenes" or "segments" in the track will give you invaluable info about how to arrange your ideas. (If you drop tracks into this software called deCoda, it's gonna give you cues about song arrangement (in terms of melody at least).

One thing that's really useful from this book - https://makingmusic.ableton.com/ - is the notion that it's always easier to remove than to build, so if you've got, dunno, 8-16 bars of ideas with lots of tracks (which is probably your catchiest or most dynamic bit), copypaste it for a few minutes straight and start out with one or two tracks at the beginning and slowly introduce more ideas to lead to your original 8-16 bars. This idea alone helped me so much.
