Will a supplier be invited by each of his osapiens-customers?

Several book-publishers order their books at the same printing companies.

If multiple publishers are working with osapiens for EUDR compliance, will these printers be invited separately by each osapiens client and have to run through the business partner onboarding process individually for each?

Or will it be sufficient for a printing company to register with osapiens just once due to something like a planned supplier pool?
