Feature request: Ability to set height offset to match actual desk height

[docBliny]

First of all, great work! I received my Upsy Desky's in the mail today and I wish setting up commercial devices was this straightforward and reliable...

I have the new(ish) paddle controller on my Uplift V2 and it has the ability to calibrate the actual desk height to match the actual height of the desk. For example, I have massive casters on my desk, which raises the desk up and I was able to set the display on the paddle to match reality.
