How to add content to more than one gated member area?

Hi and let me say, great add on; Gated Member areas. I have been looking into this and was disappointed with the lack. but now here it is! Bingo.
One question though. I can see the layout basis of the gated areas and you don't seem to be able to add the same content to multiple member areas. ie, Tiered plans of membership where the 2nd and 3rd levels would have access to the same content as the lower plans, plus some extras.

Am I missing something?
Thanks.
