AOR - Location Setup Question

Content

Just wanted to see if there is an easy way to set-up locations in the area of responsibility. 

In our organization, there are people responsible for 50 locations and it becomes difficult and time-consuming to add all these locations to someone's area of responsibility and the list keeps on growing if we add new locations to the organization. Is there an easy way to group locations in one category and someone if responsible for a group of locations we just assign a group to the individual and the person gets access to all the location in that group.
