Good to hear that blutility (which is blueprint utility btw) is helpful.
The documentation is not great for it. But you will find that any blueprint function that you create if you click on it, in your option for it you will actually have a tickbox for “run in editor” or something along those lines. Once you tick that you will get a blutility option on your blueprint actor in the game and a dropdown to select and run that blutility. Obviously this version only works for actors in game but I do most of my functions by doing it like this rather than a standalone blutility.
