Adding to networks is exactly how you do this. For filters I would do this in a similar way to "mynetworks" in the example config (with a different prefix-set and controlled by a different community number) then you can enable/disable it easily per peer. Don't filter it *out* though - default to not sending anything and just permit it to the relevant peers.
