Would be nice to be able to attach a list of custom attributes to products in a certain category. I can do this with an addon in Shopify which prevents me from being able to create my listings in 3DSellers because I have 12 pages of attributes so to much risk of missing needed attributes during product creation in 3DSellers. If I could make product creation show a pre-defined list of attributes needed for a product based on its category this would solve that problem.
