I have a workflow which assigns the tasks by pulling the information from  SharePoint columns in the item. (Approver 1, Approver 2, etc., ) These columns can have either Users or Groups in them, and at runtime it can vary depending upon the item.

The Users works fine, as it correctly assigns them and all is well, but the Groups do not work properly. The Assigned To in the Task is blank and nobody, not even the group members can action it, and no emails are sent out even though the history shows that the task was assigned to the group.

1. Is it possible in K2 to actually do the above, which is assign a task to a Group or a User from a SP column while not know which it will be?

2. If it is possible what are the settings in the Destination Rule and Set? I've spent a few hours playing around with various combinations without success.
