Well if you use my system its capable of doing this... in the example script I posted with the random example using an enum set multiple ones for different county's and city's. Then set locations and check them so if there in Los Santos Load the Los Santos Random Mission enum that has all Loading Points in Los Santos

I hope this helps if not I'm sure I can right something up as an example on how to check what area there in then everything should be straight forward from there.
