search multiple images at once

Hello,

I have a BUNCH of galleries that I need to re-create (because the old code of the galleries has not managed to be updated to the new ones).

So I would like to be able to search for multiple images at once, instead of searching and adding each image, one after the other one.

For instance, I would like to search for: “image-a.jpg, photo-2.jpg”.
I have not found any plugin to do that.

I tried to make one with chat get…but it failed.
Would it be a way to add a piece of code to make it work?
