How to delete multiple images or all images in a product

In the Product Editor  -- how do I delete multiple images (or all images) at the same time?? 

Right now it takes forever to delete 50 images, click photo, click trash can, confirm delete, wait, repreat.

I need this feature and use it all the time -- when I add a new product I duplicate an existing product that is set up how I want it, and then delete the existing images so I can replace them with new images.  But in the editor I can only delete image one at  time, which is very time consuming! How do i do this? 

C'mon guys! This is so frustrating. I connected a print-on-demand shop with Squarespace, and it automatically imports about 80 images per product (60 products). Now I have to manually delete them one by one. And the best part is, a warning popup appears with every deletion.

It is such a hindrance each time that it is making me want to switch sites 😞 I am always duplicating one workshop for the next and it takes soooo much time!

 From my research, this has been a major problem for many years and they have not addressed it.
