Eagle - Double sided PCB - Vias on top but soldering on bottom

I managed to find out how to use the trestrict an dautoroute....

I now need another solution to a problem... In home made PCBs it is good to have the same spacing everywhere so it takes about the same time for the whole copper to be wiped out.
with t restrict there wont be any copper under the components and it takes too much time for whole areas of copper to be wiped out. I need to add a copper inside every component but with no ground or anything. Just to add copper so I guarantee I wont burn any routes when I'm etching the PCB.

example:
I need the black square under the relay, to be filled in with red but with no connection ro something. Just to avoid etching for more time.
