Hm... not really. One thing I started doing which may or may not help you is to buy or get a band and wear it on your wrist. I watch would do fine as well. As long as you don't usually wear one. If you do, take it off. Then everytime you notice the new band or the lack of it, do an R.C. and keep the band in your mind. Eventually in a dream you will notice your band, or lack of one, and R.C. in your dream.

This works better than just remembering to look at your hands every once in a while because the band will always make you think of R.C.s, where as just your hands might not make you remember all the time.
