Option to Auto-Decline Free Company, Friends and Linkshell Invites

I just hate getting spam invited to join a Free Company, when you are not in one people just spam you with these. I get one every 5 minutes, and it is such a hassle to constantly decline them. It would be nice if there was an option you could turn on that auto-declined them, as well as Friends and Linkshell invitations. Some people just want to solo, or are not interested in joining a group at the time. An option that you could toggle on and off in the menu would be great in my opinion.

I know a few other games have this option.
