I think I could do it with one pcb board this way:

Make an additional schematic sheet, insert the connector and connect all
signals to it. Copy this connector with the signals and change its
refdes. Use gsch2pcb with this new connector sheet and all other
schematics. Now I get one large pcb board containing all parts and these
two connectors. Corresponding pins of these two connectors are connected
to the same signals/nets, so pcb program knows about the connection. Now
I can position the connectors and connect its pins with traces in an
additional fake copper layer. pcb program should see these traces and
use it for shorten it rat lines -- rat lines from one sub pcb should end
at one connector, and the rat lines of other sub pcb should end at other
connector.
