Points upgrades come out of O space, GUC's come from a different fare bucket and usually have more spots available.

They MIGHT make an exception when you're platinum as those support team members seem have a bit more power then their counterparts at the regular support desk. But I wouldn't count on it.
Generally more reward space opens up when closer to departure and still a lot of seats open (3-4 weeks)
