Idea 1:
Use multi-user properties for Goal contributions, such as Deal Collaborators, assigning the entire amount to each user selected. This is useful if we have BDR’s/specialists who have quotas for finding/advancing deals based on the deal amount, but do not split the amount with the Deal Owner (both Deal Owner and collaborators receive credit for the full amount of the Deal)
Idea 2:
Use secondary user properties in the same goal as main Goal user property (have more than one user property count toward a single goal).
i.e. a revenue goal has Deal Owner deals and different Specialist deals counting toward it.
