I am carrying this idea just over from the old HubSpot ideas plattform:
"Many (if not all) of our clients need the ability to attribute multiple owners to Contacts, Companies and Deals in the CRM."
"In our case we have multiple people working on the same deal. Currently all I can do is filter the deals by the hubspot owner but I would love to be able to track the ROI of individual salesmen but I get incomplete data right now because they might have worked on part of a quote that was assign to someone else because we cant add multiple users."
The problem shows up when you set users so that they can only see their assigned contacts and unassigned contacts.
The current workarounds (not setting a user or just not working in a team) are... less than satisfactory. It would be great to hear when this change comes.
