Currently, any package (hosting plan) we create on Ploi.core will have a minimum of 1 website (understandably), however, sometimes we sell add-ons, so it would be nice to have a way to either create add-ons (so customers could add them to their current plan) or at least the ability to create a package with ZERO websites, so we could add multiple packages to the same customer, to cover the add-ons, without adding extra sites.
