I do the following:
1. Assign all I/O in the schematic.
2. Generate a pcb file.
3. Look at the layout at point out potential problems.
4. Go back and alter the schematic connections.
5. Regenerate the pcb file (just a new net file).
6. Load the altered net into the existing pcb layout.
7. Repeat until satisfied.

I don't know how you could tell gschem that you don't care about 
connections? What would your final schematic look like?
