The third possibility would be construct a switch block that takes n inputs and has a method to select the input by a number.

I think gnuradio needs a mux and a demux block. A mux has N inputs and a set_n method. The mux will only feed the output with the nth input stream (throw out/ignore the other inputs). A demux has N outputs and a set_n method. The demux will only feed the nth output with the input stream.

Exactly what I was thinking about. AFAIK the squelch block has an option to output either zeros or nothing when squelched.

I would not call it multiplexer, as this implicates for me interleaving of more than one stream to of from. I think our searched-fore behaviour is rather a selector or multiswitch.
