Default Help with international roaming. Need AOSP "home only" setting. It's there an app or

New to posting on here, so be patient... I have been flashing roms since the Motorola droid 1 and love the mods we can do to our phones. Now I have a Samsung Galaxy Note 3 on Verizon, so no root yet. I work near the Mexican border where it easily switches to roaming. My question is that on CM roms (AOSP) I'm able to go into roaming settings and select either Automatic (default) or Home Only which will prevent anything but a Verizon signal. Works awesome. I don't know why this is unique to CM or AOSP roms and not touch wiz. Is there a way we can have that added or even an app that will do that very thing?
