Booking a stopover on one way saver award

[hsf]

I understand that on a one way saver award, there is no complimentary stopover.

Does anyone know whether you can pay 10000 miles to get a stopover?

If so, can it be done online, or does it have to be over the phone? (Does 15% discount still apply?)

can you not book two one way redemption? one to your stopover, and another from stopover to destination

The different zones probably don't make it very worth it to do it this way for the OP
