Create Dynamic Group using existing Template
To create a new Dynamic Group using an existing template, click the next to the Dynamic Group name and then click New Dynamic Group.
Alternatively, the New Dynamic Group... is accessible from Admin > Groups. Select a group (in the Groups pane) and click Group at the bottom.
A Dynamic Group Wizard will appear. Enter a Name and Description (optional) for the new template. Users can also change the parent group by clicking Change parent group.
Select Dynamic Group Template from the pre-defined templates or select a template you have already created. Click Choose from existing and select the appropriate template from the list. If you have not created any templates and none of the pre-defined templates in the list suits you, click New and follow the steps to create a new template.
The last screen is a summary. The new group appears under the parent Static Group.
