I am not sure you can. I believe if you change the company name on the template; it changes it on all invoices period. At least that was my experience. My personal work around since I have another company that invoices once or twice a year and not worthy to have its own accounts, ect is making the template very simple and then use different company logos in the template design and remote the company name and any other info that is not the same; i.e. phone number, address, ect.
