Editing a published summit (or making a summit a draft)

We are looking at hosting a summit through Zoom Events, however in getting familiar with the setup, we found that once we published the summit, we were no longer able to go back and make adjustments.

We anticipate that as we approach our event date, some adjustments will need to be made in the sessions themselves and the speakers, or that we may want to include different text in the description or other aspects of the summit, yet I could find no way to make any modifications other than removing the entire summit and starting over.

Is this expected behavior or are we just missing something? How do others handle this? We don't have all of our speakers nailed down yet, but we'd like to start setting up speaker bios, entering in the schedule, and allowing those who have already committed to start practicing, as well as opening up our lobby earlier rather than later.

I don't see any way to save a summit as a draft either (in other words, entering in data and uploading pictures, but not pressing the publish button at the end and just saving.

Your help is so appreciated!
