Is your proposal related to a problem?

Whenever I create a new managed event type I have to copy over all of the settings from one of my other event types manually.

Describe the solution you'd like

Add the ability to duplicate managed event types like collective event types.

Describe alternatives you've considered

Not using managed event types, but they are necessary for the current setup I have because I need to protect permissions and have them show up on the calendars of individual team members but still be tied to the team.
