Does Primavera Unifier API have any upsert (create or update) option?

Hi -

Requirement is from source system if data comes (with unique identifier) then we want to update the Unifier BP record if data for unique identifier already exist, and want to create BP record if data for unique identifier not exist in Unifier?

Current way which I know is, use the get/fetch BP record API or get UDR data API and in the middleware run the comparison and then take action like insert or update.

I'm looking for some Unifier API which work like upsert operation, like we'll pass the unique identifier in upsert API, and base on record availability it will take insert or update operation instead of middleware doing this.
