It is now possible to assign an action item to more than one person -- something we've had a few requests for!
You'll see this functionality when taking notes in a meeting, and when editing the meeting record after a meeting. The "Owner" field now allows you to select multiple people. It also looks quite a bit different, but you can still search for a person by typing part of their name.
When you save the action item, we create a separate action item for each owner.
