Custom Executable with buildDir

Would it be possible to run custom executables so that it would work with the default Working directory %

{buildDir}. For example, if you add a custom executable and select the qmlviewer.exe to the Command field %{buildDir}

is set as working directory. This does not work if you don’t define the full directory to the working directory field. There will be “Failed to start program. Path or permissions wrong?”
