On my server, I can start two services like this:

gunicorn -w 2 server:app1
gunicorn -w 4 server:app2

But this requires two lines of commands. Is there a method that I can use only one command to establish the serivces of app1 and app2, where app1 has 2 workers and app2 has 4 workers?

Here both of app1 and app2 is expected to use same port.
