Yes, you should be able to set up an io_signature just like any other block. You should then be able to use self.connect(block0, (self,0)) and self.connect(block1, (self,1)) to connect them up. Or the appropriate C++ version for this. The main restriction is that you cannot have a variable number of streams. So if you use 2 output streams, you must use io_signature(2, 2, sizeof(...)) and then make sure both streams are connected in your graph.
