I find that the specification for sheet size in the step and repeat function too limiting because it does not allow 12x18” or 13x19” as I commonly use. Is there a way I can change or edit these sheet size option to include my size preferences?

Hi Steve,  
Adding new sheet sizes in the Desktop version is rather easy and described in our online documentation:

Best regards,  
Marc
