Location-Allocation with maximum supply constraint and automatic site selection

I' m working here on a service allocation problem.

I am constricted by a certain number of potential facility locations (9) and a maximum capacity of each facility (100 connected demand points).  In total I have 500 demand points.  Now, I want to automatically select  5 optimal facility locations (out of the 9 potential locations), so that each facility has 100 demand points allocated. The selection should minimize the total travel distance between the facilities and demand points.

As far as I found out, there is no way to do this with the network analyst, as there can be no max. capacity for facilities defined in the location-allocation tool. Is there any script or work-around that could do the job for me?

Thanks for your help and best regards,
