Add to last playlist Shortcut Key

Use case scenario:

Was chilling last night with my full catalogue and shuffle, eyes closed, monitor off. Heard a few tracks I wanted to remember about before nodding off but had to turn my monitor on to add to playlist. Would be great to have a shortcut to add the track to the last added to playlist.

I have my magic trackpad 2 setup so I can control roon without looking or using a physical keyboard. The add to playlist shortcut is the missing key! So far on the trackpad I have it set so that the bottom left corner click goes back a track, bottom right corner goes forward a track. Three finger click pauses/plays. Four finger click opens search and brings up virtual keyboard. Top left click goes back (like clicking the back arrow), top right corner click goes forward.

Anyway, just an idea.

Cheers.
