Default Is there a way to change PRL's

Has anyone come up with a way to change PRL's? This is my first LG device (coming from HTC EVO LTE). I miss having the option to flash a PRL which permits VZ roaming as well as being able to force roam the device like I could do on my EVO; especially since Sprint's coverage has been horrible lately (they keep blaming it on upgrades to the towers); had them send me an AirRave for the house and my signal still completely goes away every few minutes.
