I just had to jump in here and say that it is a simple and great idea that works, and suggestions like this is what this site is all about!

Good on 'ya, RM!!! :-) (And everyone else who constructively posts on this site! ... including MG above. Contributors throw out ideas, and they may not quite work in a certain situation, or they may work perfectly, or they may stimulate the person who actually owns the system with some new ideas to incorporate.)

Excellent! :-)
