I have 2 questions So. As a graphic designer I am creating a quatation template for my client. I can send you an excel file. Question N1 : do excel has an option to create a proper cover, or I just have to insert an image directley to te sheet ? Question N2 : can I lock ( not freez tool ) some of the inserted images and also vertical section lines, that my flient could only add horizontal lines but not mess up the desing.
