After an item is created you can always start using a cover sheet for it.
Go to the item screen for the subject meeting.
On the left side of the screen, find the Item Data block.
Find Using cover sheet. If your access privileges allow you to change the cover sheet settings, the switch to the right will be enabled.
Click the switch to turn on using a cover sheet.
When you turn on using a cover sheet, the message below the cover sheet switch will indicate if you are using the automatic cover sheet or an uploaded one.
