Is it possible to request specific attributes of a flowfile from a remote process group?

Hi, i have a dataflow in a RPG that ingests data and assigns attributes to each feature in the flowfile as shown below, before transmitting to the main NiFi server. What i am trying to do is make a request from the main NiFi server for a particular attribute "P1" for example. So if i made a request for P1, (via python script or listenTCP) only P1 would be transmitted from the RPG to the main NiFi server. Is there a way of doing this, thank you.

Hi @Wynner.

I have it kind of working with a python script and command line arguments but i thought there might have been a more straight forward way of doing it. Thank you for the reply.
