When you look at the Amateur Radio Repeaters at the state level, they all appear as a text list. This led me to believe (incorrectly) that they were not also listed under the appropriate counties.
Sorry - your system of entering them appears to be quite nice. I'll have to try to do the same with Massachusetts.
That list is generated by the system based on all Ham entries in the state. The typical place to enter a Ham repeater would be in the county where it is located.
