I use the ArcGIS 9.3.
Is it possible to set the priorities of facilities to adjust the service area when those areas are overlapped ?

for instance, facility A =1 (priority) & facility B = 2(priority)
if these 2 service area are overlapped, I want to keep the whole service area of facility A as well as the service area of facility B without overlapped part of service area w/A?
