Hide Approval/Rejection from Club owls

Hello!

This is mostly a suggestion to help some of the HoHs, but also those people with active clubs.
The idea is simply just that there should be a setting in the club settings, which would allow the owner of the club to hide the owls for themselves, when they are sent out. This is already a thing, when sending out multiowls, so I don't feel like the idea is too far fetched.

It is just to make sure that owners of clubs (mainly HoH) won't lose any important owls in the mess of multiple pages of: "Club Application Approved."
