Wavetable synth trick + feature request

for any given audio, if you set the playback loop heads small enough, you can still drag it around while playing the audio, which lets you use audacity like a wavetable synthesizer.

I did an external recording with OBS seen as how audacity currently can’t record itself, the request is the following: would it be possible to make it so that the loopback feature has an option where it alternates playing the audio normally and in reverse? this would help with making the audio not clip as much and would honestly make this trick much more valuable.
