I have inherited a Concrete5 site with the eCommerce add on. Some products have Customer choices that are based on volume with different purchase values. i.e. 25 litres 50 litres etc. The zone based shipping add on has been added and we wish to charge shipping by weight.
My question is it possible to add a 'weight' field to the Customer choices so that it overides the global product weight attribute and is used in the shipping calculation?

TIA Andrew
