So each time you move the wheel, it ‘presses a button’: ie triggers a single event, which will be either to increment or decrement the elevator trim by a set amount. As you spin the wheel it triggers lots of these events, one after another. Now you can’t change that, but what you can change is the value by which it changes the trim for each event. So in the screenshot above, if in SPAD I edited the event to alter the value to 0.006, then the trim will change a lot faster. You just need to experiment to find what the right rate is for the given aircraft - 0.003 works well for fine trimming in a Kodiak.
There is a way of accelerating events so that when you start spinning a rotary dial it will get progressively faster, but you cant do that with a ‘button’. Thats a hardware limitation of the Bravo.
