Most of us who do have LW Pro, we bookmark our personal downld page. So, when we get warning of an update, we go to the browser bookmark. But I see where you're coming from. The problem would be however, that each pro user has their own personal downld page. So it would be very difficult to link the LW Pro program to each person's personal downld page. Doing so in any case would pose a major security risk. AFAIK
I've never noticed about non pro updates being different to pro updates since they're usually (but perhaps not always) released at the same time.
