RE: Attributes based pricing and production
Firm the descriptions the fit, form and function, of each are different, so I don't see how you can mrp plan or stock control these under the same item code.
If it that is not an issue for you, then its possible to add more configurations by code,
You can use more item codes together with some configurations so as not to need so many item codes.
You could also concatenate two configurations to one e,g if you have one dimension relabelled as 'shape-size' then it might have values of "round-big', 'round-small', 'square-big', 'square-small' etc.
Attribute costing is only available for formula batches. You could set up a unique batch for each combination I suppose and just keep making against that same batch
