Once you get the track edit view, rather than a big picker window have a simple picker that is docked in the VST and just drag n drop the tracks you want where you want on the timeline, these can be copied, re positioned, resized, previewed, regenerated single item selected items or all items, they will drop as 1 bar and can right click > Entire Track
You can set the color of the item for a quick visual to see where it repeats on the timeline
You can adjust the volume for one section of a RealTrack or adjust the same for all occurrences of that RealTrack
These can be in a lane under the actual waveform sections track
