Sorting / Cleaning Page prebuilt layouts

Hi,

Thanks for your great plugin.

I’m trying to use the prebuilt layout to select what I have done on other pages, unfortunately, I can’t identify the one I need :
In the “Clone: Pages” part, I have about 10 layouts with the same name, same image (or no image).

These layouts seems to be multiple (older) versions of the same page.

Is there a way to clean/reset the stored layout, so I can find only the one from published posts and pages?
Or maybe a way to preview the layout before using it?

Thanks
