Since our sales process is built around resellers we have 2 different pipelines. One for sales with end customers and one for the contract with the resellers. However, now we would like to know how much sales with end customers a reseller made. Therefor it would be a really nice feature to be able to associate deals from different pipelines with another.
In my head the feature looks could look the same as how a company is associated with deals. A field on the right side in the deal view.
