I like the new custom collection feature, and want to separate my collection into new custom categories, e.g. DVD, Blu-Ray, TV Shows, Music.

If I right click on a single item I get the option to Move to and then I can select the appropriate custom category, and successfully move it to the category.

I've tried selecting (press space or click on the tick box) more than one item in the collection list, and following the same procedure but it only moves the dvd I'm highlighting.

How can I move a number of items without having to do this on every one?
