Using Postman HTTP + WS and protobuf without internet access (no GRPC)

Dear all,
Tks for this great tool which is postman. We are planning to massively use it for a large projet but our ecosystem is slightly different than normal use cases.
1/ We do not have internet access, so only use of Scratch Pad (websocket feature is not available) on the dev env
2/ We will massively and globally use protobuf definition for all our services (no GRPC usage), only HTTP and WS exchanging protos. Is it foreseen to have kind of ser/deser capabilities in the postman UI like Protoman does for HTTP ( GitHub - spluxx/Protoman: Postman for protobuf APIs ?
Tks you very much for your answers.
