Ups rate for multiple pkgs.

As of now my UPS calculations will not work if the weight is over 150 lbs. But often a customer gets multiple pkgs that weigh 30 lbs or so but total >150. Is there a way or extension that will go ahead and calculate shipping based on multiple pkgs. of under 150lb each but totaling over 150?
Thanks

You would have to make your own custom changes. Or there are UPS extensions that support multiple packages, may one will work the way you want it to. http://www.opencart.com/index.php?route ... search=ups

UPS Deluxe should work for what you need. You can contact Qphoria is you have questions about it, by using the "contact this developer" link on that page, or by posting in the comments section.
