Add custom Agenda Item Types

Currently there are three options available to choose as Agenda Item Type": Break, Time Marker, and Schedule Note.

I am using these Agenda Items for a different purpose. I use them on the home page of an Ongoing Event to create a list of Upcoming Events.

I have to use the Translate function to show the correct event information, instead of “Schedule note”. It would be great if we can add our own custom Agenda Item Types, close the color, and choose our own Icon.
