Please add a feature in CU to notify the user that there are stub products in Seller Central?

[Products that only exist on Seller Central (not in CU nor Magento)]

Ideally in a notification area (this could be a new feature in its own right). (Nice to have) 

Ability to:

- click into it and pull up list of stub products. (Nice to have)

- remove these from Seller Central (all or selected). (Must have)

- map and merge these to existing SKUs in Magento to update qty. Search, select, match/cancel. (Nice to have)
