How to have separate folders for each app's static files in Django

When I run python manage.py collectstatic, it puts all static files from different apps together in one location (STATIC_ROOT). I would like to have a separate folder within STATIC_ROOT for each app. For example static files from app1/static should go to STATIC_ROOT/app1 and static files from app2/static should go to STATIC_ROOT/app2. One way to do this would be to create a开发者_如何学Cnother subfolder, i.e. app1/static/app1 - but I was wondering if there was a better way to do this.

I usually put them all in one directory like the following just like how I work with templates:

MyProject/staticfiles/app1
MyProject/staticfiles/app2
MyProject/staticfiles/app3
