Item Descriptive Flexfields (EGP_SYSTEM_ITEMS_DFF) mass update in items

Summary:

We currently have the following attributes defined under the Item Descriptive Flexfields. We'd like to update these attributes across multiple items using the Mass Item Changes feature within Manage Items. However, these attributes do not appear to be available in the Manage Item Class import formats.

Would it be possible to include these two attributes in the Item Class import formats so we can perform a mass update?
