Is 1 finger drag possible on a TouchPad?

I bought a Wacom Intuos Pro which I hope to use for PDF annotation with LiquidText.

Wacom implements dragging using 3 fingers. I was hoping to change this to a 1-finger drag with BTT, but BTT does not seem to have this as 1-finger gesture option.

Is there some way to do this?

have you ever figured out how to change 3 finger drag? I'd like 1 finger as well. Maybe there is a reason to stay with 3 finger? If so, I'd like to know why. I've seen this posted in other places, but never any replies.
