I'd love to be able to look at Twitch events and have an option to "use previous event as a template" for times, games, and possibly description. For many of us that stream the same game consistently, it'd be a great time-saver and encourage people to use Twitch events more.

Ideally this would be a drop-down or dialog that would pop up with previously-saved Twitch events, and would import start/end times, games, post images, or more. Specifics could be chosen through checkboxes for specific details.
