Marketplace Rewards calculation - Partner ID or Publisher Level ?

Hello the community !! 

Hope you're keeping awesome !! Nice revamp !

We’ve recently acquired a few start-ups and want to understand the best way to integrate them for Marketplace rewards.

Couple of things we need clarity on:

Are rewards calculated at the Partner ID level? If so, we’d set up separate Partner Center accounts for each start-up to maximize coverage.

Or is it at the Partner Location ID/publisher level? In that case, we’d add them as Partner Location IDs under our current Partner ID and create publisher profiles accordingly.

Have an awesome day !
