Issue Stream Command to Radio without 1:1 Endpoint

In my application, I have a transform that I do at the radio block such
that the 4 RX ports turn into a single stream of data.

I want to issue a stream command to each of the 4 RX ports, but I only have
a single streamer that it'll be outputting to.

Is this paradigm possible with RFNoC, or do I need an EP for every RF port
such that I can connect to the endpoint and create an RX streamer?

Thanks,
Brian

Replying to myself since I just didn't see it beforehand. It seems like
instead of asking the streamer to issue the command, I can ask the radio
controller itself to do it for me as per:

I'll give this a shot to see if it does what I want to do. Sorry for the
chatter.
