Pricelabs, OwnerReservations, listing sites

Okay, as an experiment, I would like to have pricelabs determine prices. I believe ownerreservation can push different prices to different listing sites such as $100 to abb, $120 to vrbo and $130 to bdc.

What would be the ownerreservations function to vary the price Labs pricing to different listing sites?

It is price mark up /mark down percentage on given channel settings./
