Hi

It is not directly supported. It may be possible to use a trick with
static recursive route - add a static recursive route pointing to an IP
address in the conditional range using a static protocol, then filter
it out based on value of 'gw' property. Note that it must be done
in export filters of other protocols, not in import filter of
the static protocol.
