One Call Now imports contact information from MMS. Most groups should be formed from within MMS fields and categories. A lot of the data in One Call Now is overwritten with MMS data on a nightly basis, so it is best to make all changes within MMS.
However, if it is necessary to add a contact to a particular subgroup,
- click Manage Group and then click Manage Subgroups.
- Click the Edit Subgroup icon (below) next to the subgroup you wish to modify.
- Set the Display Members to All.
- Locate the desired contact(s) to add to the subgroup.
- Click Save.
