I had same question because I was recommended different schools during the interview so I reconsidered my choices. And I asked about it through DAAD-portal and got answer like this: "New programs, which do not defer from the subject initially chosen can also be approved after receiving the scholarship. For approval, you will be asked to upload an updated version of the form: "Profile of the chosen study programs" and the program descriptions of the new study programs, like you did with the initial submission during the application procedure. "
So no worries
Let's hope that tomorrow we hear some good news
