Drag and Drop multiple images

I work with ceramic tiles and I have a lot of texture variations of each ceramic tile model. When I create a material I need to use these image variations. We are speaking of 8 or 16 different images.

You can drag and drop one by one from the windows file explorer but would be wonderfull drag and drop the 16 images at time. The node editor would create 16 different image texture node. Now if you drag and drop various images only one is created.
