Build release and debug with dub

[Suliman via Digitalmars-d-learn]

Is it's possible to make rule, that allow to build two version of 
App? One release and one debug at same time. I looked at 
"buildTypes" https://code.dlang.org/package-format?lang=json

But it's not possible to set different names for output files. I 
want to build App.exe and AppDebug.exe after simple command dub 
build.
