Does a module exist that would allow a store owner to input the product dimensions for each product, and then upon checkout:

1) Module goes through all items and multiplies quantity * dimensions
2) Calculates total cubic inches for order
3) Divides total cubic inches for order by the amount one palette can handle for shipping
4) Updates shipping cost and displays number of palettes being used?

If not, I'd pay to have that module built! Send me estimates via PM
