Use Case: Looping audio tracks

It would be nice to have this feature for the following use case.

When an audio track is imported, dragging the left edge (trailing edge) with the mouse, the audio is repeated. I mean is a continuous loop.

This helps when you import a backtrack for docs/tutorials etc, which is normally a short audio (16 measures) and you need to extend it to the whole length of the project.
Instead of copy and paste and dragging into position each time, just drag the edge.

Please here below an animation that shows what I mean.

up?

I'm wondering if this will be implemented one day. It helps a lot when you import backtracks that should be looped.
