Event ActorBeginCursorOver with multiple actors

Can anyone help me with a following problem: I have a lot (say, 30) actors, and when cursor is moved over one of them, i need to run a script that change material of this actor. So, my question is how can i do this without copy-pasting the script 60 times?

you can make a parent BP, then create one child BP for each of your actors
just right clic on the parent, then something like make child, the child will have all custom event and variables from the parent

Thanks for your reply mdonge!
My problem was that i tried to put the script into the level BP instead of actor BP.
