[4.7.2] How to make UE4 only start VS2013?

Hello guys,

I have VS2012 and VS2013 installed in my machine (both Ultimate edition).

When I create a new C++ project, UE4 launches VS2012. But if I select “Add Code to Project”, it launches the VS2013.

Is there any place or file where I could set up UE4 so that only VS2013 would be launched?

Thanks in advance
