Connect multiple FIX sessions with Fix Server

Hello everyone,
we are currently working on connecting multiple FIX sessions (3 connections in total - 2 for the orders flow and 1 for the market data) from our AWS server.
We initiated a FIX session and now we want two establish 2 more connections.

What are the implementation changes that we have to make?
In particular, do we need to have multiple python snippets/quickfix config files?

I am eager to know your thoughts on this in the fortunate event you already had to deal with a similar situation.

Cheers,
Marco
