I've seen a mechanism for achieving this recently on another tool. You can add run-time attributes to each gate such as "GROUP=FPGA1" and then during annotation only parts with compatible attributes can/will be put together. This could also be very useful for defining components in isolated regions ie. "REGION=ISOLATED 5V" or some such. I'm not sure, but I think that the Protel database structure should be able to handle another field(s) - perhaps there's a DDB expert who could comment...
