How to separate the node types at ecommerce module?

Hello.
I´m trying to separate the node types in ecommerce module, so that i can configure the generic module to interact with event module, but not the file module.
Currently all I have is the possibility to choose if i want "products" to interact with event module. Within products there are the generic type and file type, and i just want the generic type to interact with event, not file.
Does anyone know how to do this?

Regards,
Albion
