What Disney cannot do is combine non-matching units. As such, if you are looking for a 200 points in the March UY at VGF, and Disney repossesses a 50 points in Unit 01A (April) and a 150 points in 04C (August), Disney could offer you a 50 point, and separately, a second 150 point contract. Both would carry the March UY designation, but they would be unable to combine these two units into one 200 point contract for you. To combine contracts, it would require the units to be the same (irrespective of their now meaningless UYs).
