11 month booking resale

Hey all

We originally bought 150 points direct at RR to get the blue card, and are about to close on 350 resale at SSR, bought for the flex and cheaper dues as we like to bounce around. All contracts are December use year.

Could we also buy a smaller contract at our preferred property to get the 11 month reservation and use our points from RR and SSR?

Also, can we use our SSR points for 11 months at RR?

TIA
