Customer 'source' application names


We currently access twitter through the product ‘Gremln’ (formerly Twaitter). We are developing a white label version of our software for marketing agencies. They have expressed interest in having their own customer ‘source’ application name when posting through our application. Currently all posts say ‘via Gremln’. Is it possible to apply (or help our white label customers apply) for new application names when they use our system as white label? Example: GoBrandGo marketing would like it to say “via GoBrandGo”. Thank you for your assistance in this matter. Its greatly appreciated.
