Nathan,

Yes, this can be handled in gschem with a hierarchical design.
Basically, you will need to design a generic filter block as a schematic
and additionally a symbol to represent your schematic page's
connections. In your master schematic you will place the symbol you have
created and gnetlist will read your filter block. Gnetlist will also
modify the net names to generate a flat netlist with the names being a
concatenation of the instance name and the original name for each
instantiated filter.

You can get the details from the gEDA FAQs and searching for Hierarcical
schematic.

Good Luck,

Joe
