I love ya man!!! Oh please, oh please!!!! This is the kind of data we need. I'm about to buy a new PM program for billing and other PM functions because this is such a needed feature. It is why so many of us have been asking for a good PM module inside and as a part of AC.
With the way the business side of this business is going you really can't run a practice properly and responsibly without such tools.
Good luck and keep us all in the loop...
