Enable a quantitative way to record the fact that the same support rep got an idea from multiple customers, multiple times. Merged

Often times, the same CS rep gets the same idea from multiple customers.
- The same person can't vote an idea multiple times
- Attaching issues or comments doesn't help the idea to get bumped to the top
- Asking the customer to go to AHA to vote is too inconvenient and not all customers remember to do that. 

Aha should be able to capture that information and then be able rank ideas based on that input.
