Copy Categories between images

[mkc73]

I would love a button that allowed the user to copy copy all categories to the selected images.

At the moment I select two (or more) images in the browser and then can see the image categories in the Assigned tab - shared categories are greyed out, others are white. I want to copy all categories to both images so I go through the assigned categories selecting the white ones. For a lot of categories i.e where one image has no categories assigned yet, this takes some time and, if there are shared categories, I invariably hit one of the greyed out ones, which deletes the category from both images.

How about a button on the Assigned tab that shares all categories between the selected images i.e turns them all grey?
