Yes you can... as long as you have the albums showing in LIST view (ie right-hand pane)! To do this either view ENTIRE COLLECTION, or go through the tree view and MARK (space bar when album highlighted - will highlight in yellow) those albums you want to bulk edit. Then go to the LIST menu, and VIEW MARKED ITEMS. These will appear in the LIST view pane, ready for selection and bulk editing.

Having no official help might be a bit of a hassle, but we get around it. Did you try searching the forum? It's pretty effective, normally.
