Why would you copy a unit like this?

If you want to make changes to a unit file I recommend copying it from
/lib to /etc and edit it there, but that while keeping the same
filename. 

Why would you want top copy a file and rename it? What's your usecase (I
don't doubt there is one, I am just curious).

(But yeah, as you noticed %n is what you are looking for.)
