Email a design, Download/Print other design

I have a simple Question.
I want to create an email with link to my invoice ninja invoice “design 1”, and if client/Customer download the attached invoice in email i want it to be “design 2”.
is this possible, and how to set it up, if it is not possible……will it be an option in the future?
Due the graphical layout online, it uses some toner needed for printing and as IT/ELEC/REPAIR Technician?Salesman i have clients complaining I sell these toners 2
