The referral source system, unless im missing something, doesnt track return customer numbers. I want/need to be be to see how many of my exisitng customers are coming back each month, having imported 10000 clients into RS I now have no way of effectively tracking who's already in my database and is coming back.

Referral source should be set ONCE when the client is created say "google", or "passing traffic". Subsequent tickets from that client should add a +1 to the "existing customer" count for referral reports and not the original referral source.

This is really going to screw with my ability to track return customer if this isn't implemented in some way
