Just a thanks for KVS for making this addition. The awards shown in the tool via the CX site are indeed the inventory available to partners, at least AA and at least universally across the board for all the flights I've searched.
Probably wouldn't have bothered to put together the YYZ-HKG-MNL-HKG-LHR F award that I did if KVS tool hadn't made it so easy... ^
