To import virtual minute book headers from an existing entity, go into the profile of the entity for which you would like to add the headers and navigate down to the Virtual Minute Book tab.
Once you're in the Virtual Minute Book tab, select the + in the left panel and select Import Headers in the dropdown list as shown below.
Once you select Import Headers, a list of entities will appear (including template entities) in a new window. Select the entity from which you would like to import the headers. Once you make the selection, the tabs will automatically be imported to the virtual minute book of the new entity.
You can move/edit/delete any of the headers by either dragging and dropping them or by clicking the three dots on the far right of each of the headers as shown below.
