CalDAV: Bind calendar to certain item and value


I would like to bind a calendar to a pre-defined item and a pre-defined value which is assigned to the item at the beginning of the event.

The reason is that I do not want to put information into the summary. I just want to add events to a certain calendar and every time the event occurs the same action should be triggered. I have a separate event for each action to be triggered.

Thanks for your help!

Kind regards
