Is this option only available if you haven't already worked with a client? I have a client who was basically horrible and he's asking about more work. I'd like to be able to block him but I am not seeing this option where it's shown in the screen cap above. I see add to group but nothing below it.
Blocking jobs posted by a certain client from showing in search isn't currently available. However, we've shared this idea with Tam's team and they will consider it in the future.
