How do I press a button to emulate one tick of mouse wheel scrolling?

[OutcastOrange]

I mapped the scroll wheel to a face button on my Xbox controller. The issue is, when I press the button only once, I get many inputs very rapidly, instead of just one. I would like it to function more like a keyboard key, where you get one input per press.

The very simplest thing I would like is press a button once, scroll one 'tick' on the mouse wheel.

The specific face button is the left shoulder button on an Xbox controller, and I'm trying to map it to mouse wheel up.

I've experimented with the advanced assignments, and I was able to get a partial workaround. I created something like this:

[pause 0.2 ms] , [mouse wheel up]

This partially works, but now there is a delay before each button press is registered. I'd prefer something where you get the button to react immediately, but there is a short delay before it reads more input from the same button.
