Django manage.py: create run configuration

I am trying to create a run configuration so I can run Django's manage.py utility with the shell option to bring up the shell, becase the built-in manage.py option doesn't work for me (I need to run a different manage.py). I tried setting up a run configuration with the other manage.py file but when running it, it simply doesn't work, the console is just stuck. What can I do?
