Creating a view of all content in a nested group hierarchy

Hi,

I have a structure of nested groups that each have different content attached to them, and would like to create a view that shows all content of the selected group and the content in it's child groups.

I use og_subgroups to propagate permissions trough the structure but can't seem to find a way to create the view.. Is this possible with Organic groups, or do i have to write a module myself that provides this feature.

I would by the way need the same feature for members of the groups and sub groups.
