Yes, thank you davegee, it is clearer, but with that what is achieved is to change the style to another category, it does not create a duplicate of the style, in order to have one in its original category, and another in the category "2 images".
I had understood you, that this process was to duplicate the style.
I don't know if this is a good idea, it can be done, but it is a long work, I think that having an option to select different listings with different blocks of images is more practical and it would save a lot of time in searching for a certain style.
