Users have the ability to flag items to sync to e-commerce by the type of product or item as well.

When you navigate to the Administration page, and select Item Types from the navigation. You can expand the category you would like to have synced.

Pick one of the options in the expandable section, and if you scroll down you have the option to sync all of the products and SKUs related to this Item Type over to your e-commerce app.

Selecting ‘Include in E-Commerce’ triggers this whole Item Type to be sent over to your e-commerce application.
