Change default skip length?

I’m using a Logitech Harmony remote to control my Apple TV 4K. It doesn’t allow skipping through video with the directional left/right buttons (or FWD/REV buttons) in Plex unless you press pause first. I don’t know if this can be changed in any way, but more importantly, when pausing and then skipping, it does so in 10-second intervals. It would be nice to be able to change this default to something more useful (like a 1-minute interval forward, 30 seconds back). Right now, the only way to skip to the 25-minute marker of a 50-minute clip is either press forward 150 times, or find my original Apple TV remote.

I would like the option for it to be changed. For my use cases, I’d like it to be something more like 3s or 5s.
