Filter nodes by context in views?

We are increasingly using Context to define site sections. We'll generally provide a (bulk operations) view to our site editors and contributor to filter and review content (nodes). We generally take this approach so these roles don't need the administer nodes permission and in turn don't need to use the standard content/node/overview page.

I was beginning to think that it would be useful for these roles to be able to filter their content by section (context), in effect having a section manage. I've had a look around to see if there is a context filter for views which can be exposed.
I haven't found anything yet - can anyone share an approach, is there any way to do this in views with exposed filters?

Many thanks
