How can I make a signal that can be edited like an exported variable

I'm trying to make one reusable that I can use for all the things in my game by using a lot of export variables. This has worked up until I had to use signals to accomplish what I'm trying to do. The signal emitter is on a separate script, and there is multiple of these scripts that emit different signals. I want the signal receivers to have the same script but change based on what I put in the Inspector. How would I do that with signals?
