Yes, you bet you can! Your account's Spec Template can be edited by Super Users only. Super Users, look to your "Firm Nav" drop-down in the upper right corner of the screen within the black header bar. Select the "Spec Template" option from the Super User Panel and you land on a page that allows you to customize a spec template per each category. Now when users add products within these categories to projects, the form will automatically fill-in image captions and prompt users to fill in attributes and nested products in accordance with the template for the category.
