Insert/update products with a custom price for specific location(s)?

Hi, is it possible to Insert/update products with a custom price for a specific location via the API?

I notice this feature is available in the Deliverect portal (Add custom price) but I can't seem to find how to do it on: https://developers.deliverect.com/reference/insertupdate-products-and-categories

Example scenario being a Franchise has multiple Shops with the same products but some products are more expensive at Shop B.

Thanks.
