Symfony, Doctrine Guard plugin, generator.yml file, configuration using another module

I am using Symfony 1-4 and sfDoctrineGuardPlugin.

My question is: on the Doctrine Guard plugin, you know that each module comes with a .yml generator. And I need to configure the .yml generator. For example, I need to display a column of another table (module).

// for example i am at X module and need to sort according to another table's/module column ...

config:
list:
sort: [X, asc] // x is not on my module

Same with the list / display. I need to display some column that is not in my current module ...

I could not find it on the Internet. Thank you very much for sharing the idea and / or information, erman.
