Financial flow (Claim response)

Hi all,

I checked FHIR financial flow (https://www.hl7.org/fhir/financial-module.html#order) but i’m a little confused. Based on my knowledge in insurance field payer can pay bulk of claims together with one payment reference (check number) but in FHIR schema i noticed that payment found per claim on ClaimResponse resource so how can i pay bulk of claims together ?

Regards
