Is the Parametrized API Access available for Push Transfers?

[efiege]

Is it possible that the consumer gets the opportunity to decide on the parameters that the provider sends to it's data source for Push Transfers? To give an example: The provider offers an API, which can be used with query parameters: /api/books?title=?. Now as a consumer we want to pass title=Harry%20Potter

According to

Push Transfers can be started using the TransferRequestMessage. The structure of this message can be seen here. We see no possibility to transfer this information to the provider as the DataAddress seems not meant to be used to transfer information for the source system, but just the target system:

The dataAddress contains a transport-specific endpoint address for pushing the data. It may include a temporary authorization via the endpointProperties property

And also the other attributes seem not to be feasible for this.

So is the parametrized API access available for Push Transfers?
