Hello dlishdesign,
Sorry for the confusion! I believe the intent of that feature is just what it says, remove it from the listings. The event is still available by URL (so it is not private), but it is not available on the lists of events.
I’m not sure there is a simple out of the box way to achieve what you would like. I would suggest creating a category of events you want this special filtering on, and then use theme override’s to accomplish what you want. You’ll have to change up the query to ignore that category on your selected pages.
If you check out our Themer’s Guide, you could probably make a template override to display what you want.
If you have a moment, we’d love for you to submit your idea to our UserVoice forum. We take user ideas and contributions very seriously, and many times their ideas end up in our future releases.
Does this make sense? Let me know if this doesn’t work for you.
Cheers!
