The Unit can also enter their activity on My.Scouting under the Organization Manager, Metrics tab. It just tales one of the Key 3 to enter the date.
Plus, Commissioners should not be doing unit data entry. The metrics are about the unit, not the commissioner.
Lastly, the Outdoor Activity is really an item waiting for Cub Day Camp, Summer Camp, this year. So it will normally be blank until this summer.
