French final invoice after prepayment: S4 and BT-25 missing in UBL CIUS FR

Hello, we create final invoices after prepayment through the JSON API (2026-06-26) with invoice_references of type prepayment. The reference is stored, but the generated xml.ubl.invoice.frcius.v1 has no BillingReference and keeps ProfileID S1. XP Z12-014 (cases 20 and 21) requires billing framework S4/B4/M4 and a reference to the prepayment invoices (BT-25/BT-26). Is there a way to get both through the JSON API? Thank you
