Select multiple pages and mass add/remove/change labels

Select multiple pages either ad hoc or as a hierarchy (all children of page(s) X,Y and Z) and then apply a new label or change the current labels.

This is a feature request. As part of wiki-pruning, we want to re-organize a bunch of pages. We need to apply new labels to about 60 pages. We will have to go through, one-at-a-time and click, open, edit labels. I would really like to be able to select them out of a list view, then change labels all at once.
