Sort Images in different Subfolders

Hey guys,

I have over 1000 images in one main folder with subfolders in LC and I´m searching for a solution to sort them via drag and drop inside the library. If I tried this, I received the messages that it is not possible to change the order cause images are in subfolders.

I tried to select them all and paste into a new folder, just for sorting and Web export, but it´s not possible to paste them into a new folder.

Any advice how I can sort the images to have this sorting for the export later?
