Hello,I am trying to create a hierarchical block with a variable number of outputs, but I get this error: "RuntimeError: Hierarchical blocks do not yet support arbitrary or variable numbers of inputs or outputs"
This appears to be a known issue [1], and I'm wondering what the best work around is. I think I can simply create an IO Signature with the maximum possible outputs I will need, and then connect a null source to all of the outputs I'm not intending to use. Is that a good idea?
Thanks, Orin[1] https://lists.gnu.org/archive/html/discuss-gnuradio/2009-04/msg00011.html
