It would be helpful to see if any products in the Product List (a.k.a. OverdrivePro) have subassemblies save levels other than the standard library save level. The column could be a color coded dot for the save levels - blue/green/yellow/red to match the save levels.
There would need to be a way to check nested subassemblies too.. would it be the same column or a separate one? I'm not sure if it would be useful to have a color-coded dot for each subassembly with a quantity greater than zero.. or just one dot with the color of the most custom save level.
