How do you keep control of automatic ad variations?

You let the system move the crop of the photo and you lock the text: the name, what is served and the date if there is one. The next day you check that it has not cropped out the dish or changed the offer. Mark which line cannot be touched: allergens, the menu price or the date. The automatic crop hides the dish and leaves the tablecloth. The ad with the text locked and a capture of the crop that was actually published.
