Request: Custom forward wind for tv and movie recordings

I use plex and HDHomeRun to DVR tv shows and movies on a daily basis.

Where I live the feature to cut commercials doesn’t work too well but the length of commercial times is pretty standard.

I’d like to be able to easily put a number in to the forward wind icon and press it once per commercial to quickly take me back to the tv show or movie.

Early 2021 clean-up: duplicate (same feature scope anyway)
