Assigning Categories - System should remember position of tickboxes

When assigning products to categories via Right Click > Assign Categories, each time you do this, the list of categories is fully expanded, and you have to scroll down to find the product tickboxes.

It would be good if Mag Manager auto-scrolled you down to where your product is. It would be good if only the category your product is inside, is expanded.

This wastes a lot of time, when moving a lot of products to new sections etc.
