Welcome Jon! 
You could go at the Big Hi topic for a formal presentation ^^
About your idea, I’ve seen people experiment with that, and it doesn’t work that much. The fact is, you should train yourself to be aware, more than just doing RC’s, and if you get reminded to do a RC by an alarm,you have no incentive to actually stay conscious and look for dreamsigns in order to RC. Plus such alarms don’t often appear in dreams 
so you’re out of luck.
I’d suggest instead to be actively looking for dreamsigns, and try and ask yourself during the day where you actually are, question yourself if it is really a dream or not, try and remember what you were doing, thinking, saying during the last minutes. It’s great awareness practice
Good luck on your Quest! ^^
