That's possible already, in a way. :)

We have an app to internationalize all the texts within Linchpin Onboarding and Assistant. It will be part of Linchpin Manager, but it's not completely finished yet. But if you need it right now, and if you already have the Linchpin Manager installed and licensed, please feel free to contact your respective contact person with us and ask them for a test version of Linchpin Translations, so you can try it out.

...exactly what I would like to see, too. Should be dependent of system language or personalized by profile :)
