I am agree with everything who was said above this would be super usefull !
Example from my case, because our product is sold by a distribution network, every distributor has its own deal. It could happen that few distributors send the same lead in the same period of time, so we need to identify wich deal is the main one and wich deal we have to automatically close because it was sent too late.
Before this feature arrives, i have no idea of how to deal with that…
