Try using a custom javascript snippet with something like this…
var params = arguments[0], $ = skuid.$;
var model = skuid.$M(‘YOURMODELNAME’);
var row = model.getFirstRow();
// get your billing values and populate your shipping values
var billingValue = model.getFieldValue(row,‘YOURBILLINGFIELD’);
model.updateRow(row,‘YOURSHIPPINGFIELD’,billingValue);
//etc… do the above steps of getting and updating for every field…
model.save();
model.updateData();
