Potentials and Relationship With Pipeline- Doulbe Booking

Potentials and Relationship With Pipeline- Doulbe Booking

We distributed to several customers who are all competing on the same project.   If customer a,b, & c are all bidding the same project which has the same potential name under the individual accounts of a,b, & c, is there a way to eliminate pipeline from projecting the sale 3 time overs?  If the project is a $10k sale and only one of three bidders will get the job then I would like pipeline to recognize $10k of potential revenue not $30k.  

I guess this would also apply to totals in estimate report also.
