My question is about product sizes, box definitions and Canada Post shipping module.

I have it installed and it works. I have dimensions and weight defined for every product. Is there a way to handle situations where products can be stacked inside each other or inside other products?....for example flower pots, or buying a few items and a suitcase -clearly products that can be put inside the case and be shipped as one box the size of the case. Has anyone tackled this successfully in any way?
