Material Master Field for Material Category

Hi Experts,

Are there any field esides Material Group and Material Type that can be used for Material Category? I saw MARA-ATTYP, but it is only being displayed in Retail Materials. Is there a way to show it in MM01/02/03 or any other field to do this?

Our Requirement is to create another Category for certain Materials for our Customer Report - Sales By Material.

Thank you for your inputs!
