I know I can exclude them from each individual message, but that would be very cumbersome. Hoping there is some setting or hack that would allow us to opt out selected users from all future in-app messaging.

None that I know of. We're using a tag to filter those user out.

Is there a way to opt out selected users from all in-app messaging (chats, posts, product tours, etc.) as we can for email?
