I'm sure this has been discussed but couldn't find it in search 
Situation: -If I have contracts at different resorts and enough points at both but want to have two separate vacations at the same home resort.
Can I make Reservation 1 at 11months with home resort points; then at 7 months call in to MS and swap out the reservation with outside resort points and make a second 11month reservation at my home resort?
Or do I need to cancel the original, pray it populates in RAT and grab it with my 7 month point contract hoping it isn't grabbed by someone else?
Would want to avoid needing to borrow points from the same contract.
