Another staple User Actor, especially for cases like this, is what I call a "Delay Gate"; a User Actor with a Gate that initializes off, then turns on shortly after. I use these all over the place to 'eat' unwanted triggers that generate upon entering a Scene because sometimes they're unavoidable (and sometimes it's just faster for me to throw one of these inline to eat a trigger that I don't want because it's faster than spending the time to examine everything upstream to determine where the trigger is coming from). For example, I use Delay Gates with Comparator actors and Text Comparator actors when I have their 'compare' mode set to 'Always' because you'll always get a true or false trigger out of those actors when you enter a Scene in that mode.
These are not entirely relevant, but here's a couple other groups of simple User Actor 'tools' that I find myself using quite often:
