[ESPResSo] fixing center of mass

How does one fix the center of mass of a group of particles at a specific 
point, given that the simulation uses periodic boundary conditions?

Here is how I did it:
I placed the center of my group of particles (type 1) at the point I wanted it 
fixed, then called
       inter 1 1 comfixed 1

I got this error message:
works only with non periodic BC

Is there a way for me to do this?
