How do I have menu scroll through options?

I'm trying to make a level select where when the player presses a button, it will increment the level number once, but if the player holds the button, it will continuously increment the level number till they stop holding the button. It sounds simple, but I can't seem to figure out an elegant solution to do so.

I'm pretty sure you can remove the Trigger once condition and move the Sprite conditions under the On touched event.

No criticism, just simplifying.
