My problem is that we only ship dvd's, and only use UPS.

The DVD's we ship are 3.2 OZ. each, so it take 5 dvd's to equal 1 pound. Is there a way for me to set up my Zen-cart with the UPS module so that it will calculate the weight.
At this point the module only see 1 LBS increments, so for example, if someone orders 5 dvd's the module charges it at 5 pounds instead of one pound.
I get that UPS has a 1 pound min but is there a formula or something I can use to get this closer to the correct pricing and weight?

I'm in
Zen Cart 1.3.8a Patch: 1::
with SuperOrders 2.0 and UPS Worldship 9.0 Export modules

thanks in advance,
jim
