After creating a simulated live, its settings can still be edited. In order to do so, click on the Scheduling tab.
Here you may change the starting date and time and also edit the simulated live playlist. Clicking Save changes to apply the changes.
Please note that you may not edit these options once the event is about to start, and during the event, but you can change
them again afterwards, thus being able to re-use the same livestream. You may also want to view Tips and Limitations
