actually, no worries. I'll handle it server side, ignore the request

Define the field on your ResourceModel with persist : false.

That should remove it from consideration for syncing.

Remember to listen for the eventSelectionChange on your scheduler to keep all the checkboxes in sync with reality.

You can check one which selects all the events in that resource. But then click some other event without the CTRL key and that will deselect them, so the checkbox must become unchecked.

Also, if you CTRL/click every event in a resource, the checkbox must become selected.
