How to import FCC frequencies to PRO 668

[TThomps]

Wondering what the most efficient way to import frequencies from the FCC database to my pro 668 using iscan. is there a way to go throught and pick all the businesses i want and whatnot and get them in? i would do it manually but theres hundreds in my county that i want to put into indiviual playlists and importing them one by one seems crazy. there must be an easy way. also i did just subscribe to a premium membership because i saw something about uploading database information but im kind of at a loss. any help would be great thank you all. and by the way first post. been brousing the form for a few weeks and picked up my first scanner a bearcat 125 about 3 weeks ago. got hooked and got the pro 668 a week later to get all the police and what not around the area love everything about it!
