Condense multiple tracks of Audio to 1 track with drop down tab

Often when editing, we have 6 to 12 tracks of audio [depending on how many actors are in a scene]. Then double or triple that when performing a J/L cut. We don't want to lose sync by deleting the tracks in case we need to isolate a mic or bypass a mic hit or related issue. The current methods to reduce the number of tracks is either creating a multicam or nesting a sequence--which both create a longer work around. A condense audio tracks feature would be a fantastic solution--something that will help clean up the number of tracks seen in the timeline for a faster edit, but allow quick accessibility to those 'hidden' tracks when a fix needs to be made.
