If I have Billing account type: Microsoft Online Services Program that has multiple subscriptions, one invoice per subscription is being generated at the moment. Is it possible to consolidate these invoices one per each subscription into one?

The documentation at https://learn.microsoft.com/en-us/azure/cost-management-billing/manage/mca-section-invoice mentions creating a billing profile. However, it appears that’s not available for this billing account type. But I wonder if this really is the case that I’m doomed to handle multiple invoices whereas just one could suffice.
