we do:

router bgp  5539
  address-family ipv4
    network a.b.0.0 mask 255.255.0.0 route-map set-local-community

route-map set-local-community permit 10
  set community 5539:abc

I'm not sure whether this is the "commonly accepted wisdom" to do it, but
it sounds more convenient than having to have additional route-maps on
all iBGP sessions ("yet another thing to forget", even with peer-groups).
