Add a stricter "Unavailable to Work" status

What I'd like to see is the ability to not only mark myself as busy, but also as unavailable entirely.

The difference would be that while busy simply indicates that I may be slow to respond, unavailable would indicate that I am unavailable to take on more work, and so would also block new job invitations.

Obviously I love that PPH gives me a steady stream of job invitations, but I'm very fortunate at the moment to have a client with ongoing work, which means that I'm in no position to take on more for the foreseeable future.

This means that job invitations right now are a distraction, requiring me to keep logging in to dismiss them.

I would envision unavailable being an extra option under profile -> availability, and can be activated for a fixed period only, in order to prevent someone from activating it then forgetting about it.

I don't if it would be best for unavailable status to block invitations completely, but it should definitely block any that are automatic, and inform sellers that the buyer has indicated they are unavailable at this time (possibly giving the end time for their unavailable period?).

I just think this would help smooth things out a bit by eliminating the lag between an invitation being issued and a seller having to dismiss it due to being busy, by preemptively indicating that you are unavailable.
