From my testing, you can activate and deactivate Interval Repeat Action triggers, but not Repeat Action or Handling Marker. Unless there's a better way to achieve this, there's currently no simple way to run a sequence of actions (for example, multiple actions with delays) that can be stopped once started, since Repeat Action and Handling Marker cannot be deactivated.

Using an Interval Repeat Action is not ideal either, because its timer continues looping even while deactivated. This makes precise timing impossible. For example, if I want an action to occur 60 seconds later after pressing a button (which also activates the Interval Repeat Action trigger), the action might run immediately because the timer was already running while the trigger was deactivated.

Basically, when I press a button to start a delayed sequence of actions, I either can't stop it or can't control its timing precisely. What I'm trying to achieve is the ability to press a button, start the sequence from the beginning, and deactivate it at any time. Ideally, stopping it completely rather than just deactivating it would be even better, but deactivating would still solve the issue.
