vendor competency vs price profile

Hi,

We have some vendors with multiple price profiles. This works great. 

The problem is that the competencies are for all price profiles. So when one of the price profiles doesn't have a price for for a job type that is in the list of competenies the system doesn't find a rate. But it does show up in vendor selection rules.

Is the only solution to copy the missing rates to all the price profiles? That makes changing a price a very difficult task. Especially when the vendor requests a price change via the vendor portal.
