Have a button that triggers a scheduled script. The script is not executing right away if it gets queued behind any other scheduled script currently running. Is there a way (already tried priority) to force the script to take control?

you cant interrupt scripts that are currently running in the queue

Could it run on its own thread?

if using suitecloud plus, you can reserve a processor for high priority jobs and only run your scheduled script high priority

We are, how would I go about that?
