You can create an item without placing it in a meeting. In a paper-based process, you may think of this as a pending item list. You can do the same thing in the Agendease control panel. We call it parking items. You can create a parked item without placing it in a meeting, or you can remove an item from a meeting and park it.
Parked items remain parked until you place them in a meeting or delete them.
Instead of deleting an item in a meeting that you want to remove from the agenda, consider parking it so that you do not need to create it again if you want to add it to a different meeting later.
If you are prepared to create an item, but the meeting you want to put it in does not exist yet, you can create a parked item and edit it. When the meeting is available, simply move the parked item to the meeting.
