I found a strange workaround. It's not ideal, but if you select a couple of points and use the Route Planner, you can click on the VFR button and then it does exactly what I wanted. It shows the airgram only up to 3000m, plus terrain!!!
Like I said, not ideal, especially for people who are used to checking the airgram at it's usual location, but it's there. Gotta love Windy!
