Smart Grid should be smarter in triple meters

Hey guys,
   This is a minor thing, but would make life easier.
 
    Whenever I'm working in triple meter (3/4, 6/8, etc), I find myself fighting with the smart grid. It wants to give me snap values of a half note, or whole note, which don't make any sense in those time signatures. I know I can set it manually, but I'd like it if it just worked. As soon as you zoom out past the value of the denominator, the grid should go up to the next logical grouping; in 3/4, it should go 1/8th -> 1/4 -> dotted 1/2. In 6/8 it should go 1/16th -> 1/8th -> dotted 1/4 -> dotted 1/2. 
 
I've yet to think of any common situations where this wouldn't just be very simple fraction math with the time signature. Seems like it could be easy to implement. Says the guy who doesn't have to do it!
 
Thanks for considering!
Mike
