What you want to use is a signal/signalwith. A real simple example of how they work together to pick through is in Sleeper's Tomb, Bittles the Lost on hail will signal Ferrin Q`Nyil to say something. On that signal, he says something and signals back to Bittles.
A bit of work and research from there should allow you to do what you want, it's not too bad. If I recall correctly, you can only pass a number, but with some creative work, you can have that number mean whatever you need it to.
If you have any specific questions, feel free, but that SHOULD steer you in the correct direction!
