Question about gr 0.9 fg->connect

Apologies if this is no longer supported - Does anybody remember
how to connected an upstream port 0 to a downstream port 1 in
gr0.9 ?

Trying to split up gr-atsc0.9, and want to connect a file source
to equalizer port 0, and another file source to equalizer port 1.

But from gr_FlowGraph.h, all we can specify is upstream port:

virtual bool connect (VrSigProc *upstream, VrSigProc *downstream) = 0;
virtual bool connect (VrSigProc *upstream, int upstream_port,
VrSigProc *downstream) = 0;
