pax8 dynamic qty subscription id

Hi guys,
I have a client that has multiple locations and want’s each location to be billed separately (one M365 tenant).
So what I have done is, one pax8 subscription per product, per location (e.g. M365 business premium is 3 subscriptions - 1 per location).

However in Gorelo, I am trying to set up dynamic pricing and I have no way (aside from qty) to tell the difference between the subscriptions in pax8.

Would it be possible for gorelo to pull in the pax8 subscription id or some other unique identifier?
