Calendar Popover Customization Possible?

I need to customize the calendar popover with quick edit functionality for users. Are there customization options for a calendar popover? It seems like there is no option to add labels to fields that are dropdowns or multi-select.

Is there a way for the popover to open as a form?

What is the best approach to enable data editing with the fewest possible clicks?

(Test Data. Not a real client)

Possibly there is a bug with some fields.

Hmmm, I’m not aware of any way to do this currently. I’ll double check with the team + pass your feedback onto them.
