Newest Products since last login

For every B2B site, we create a category called Newest items and default it as the home page after login. As we restock or add new products for clients, we put those front and center to clients to increase sales on those goods. We have to manually maintain this category for all B2B sites and make calls what to remove and when to remove it. It would be nice to see a feature that we could enable that would automagically show the newest items added to the site (or stock that has been replenished) since a users last login.
