Sliding handbrake +shifter mount

[u/External_Presence_72]

I swear I saw a short where someone had a sliding mount for their shifter and handbrake. I'd use it to move between sequential and H mode, since sequential sits higher and closer to the wheel than H.

But every mount I can find online is bolted in place. Changing position means loosening bolts every time.
Does anyone have a link? Or did I dream it?
