{label : $L("Automatic"),value: "any"},
{label : $L("Roam Only"),value: "roamonly"}
At lines 1457-1460 (WebOS 1.3.1) find:
if(payload.extended.mode == 'any') {
this.voiceRoamingModel.currentVoiceRoaming = "any";
$('dataroamingrow').show();
}
- and add below:
else if(payload.extended.mode == 'roamonly') {
this.voiceRoamingModel.currentVoiceRoaming = "roamonly";
$('dataroamingrow').show();
}

Scripting possibilities
You can use luna-send to change these settings from the command line. I run this bash (not sh) script from cron to change to roamonly whenever my phone is connected to my access point because my carrier's signal is poor where I live and calls are dropped in automatic mode.
NOTE: This Script is Only Verified to Work with WebOS <= 1.3.5.1
