HTC Vive blueprint scrolling with thumbpad

Im working on a combination lock with 3 tumblers that are rotated to get to the number, like a bike lock. and I want the player to be able to either point at or hover over (I haven’t decided which) a tumbler and then only while that tumbler is highlighted use the touch pad to scroll through the rotation of the tumbler. The only thing I’ve found are systems that compare the initial touch position with the release position to calculate the distance of the “swipe” on an axis after the player lifts their thumb. This isn’t the kind of behavior that I want, I’m looking for a continuous scrolling behavior every tick. As I typed that it made me wonder if I could somehow compare the position on the pad from one tick to the next? Multiply the difference between those two by a float to tweek the “sensitivity” and take that result and feed it into a make rotate then to an add relative rotation also updated each tick (not necessarily each tick, even) Heres a picture of the type of lock Im talking about.
