Bulk add to/remove from category function

[baggeler]

There is a button to bulk assign products to category in VM, however it does remove all previous assignments instead of just ADDING or REMOVING the new category to the existing list of assigned categories...

In my view this is a bug and should be replaced with ADDING / REMOVING selected categories to the existing categories.

I surely agree on this... damn annoying and quite useless function as it is.
