Yes, there is a way that's easier than just using user items, etc.
but I only know its name: it's called The List Manager and is
described in Inside Macintosh volume four.

Programming is like this.  Lots of times, you have to get away
from the machine and think/read about it.  Callback routines in
particular are somewhat advanced so give yourself credit for being
able to solve it.  Read chapter 4 of Inside Mac vol. one (assembly
language) for some insights necessary when you're working in C
trying to interface with an OS written in pascal.
