To my knowledge that’s currently not possible.

There is a workaround for C# by using RedirectStandardOutput:

using (Process butler = new Process())
{
    butler.StartInfo.FileName = "butler.exe";
    butler.StartInfo.Arguments = "your butler args";
    butler.StartInfo.UseShellExecute = false;
    butler.StartInfo.RedirectStandardOutput = true;
    butler.StartInfo.RedirectStandardError = true;              
    butler.Start();
    butler.WaitForExit();
}

This is basically the example from the ms docs. :)
