This would be a GREAT idea. Especially for those of us offering Live-Training and giving those who purchase a membership level as an added benefit.
I'm in need of this feature as well :)
Thank you for this suggestion! This feature request or some aspect of the functionality suggested is currently being reviewed for possible inclusion in a future update. If there is additional information, this post will be updated to reflect it.
I need also a limited number of members to a bundle. Can this be fixed?
