Is there a way to restrict CSV to only specific controller actions?

I am using the `AddCsvSerializerFormatters` right now and from what I understand, my entire server will now support CSV input/output. But I want to be more explicit about when this is allowed because I have some pretty complex objects in some of my actions.

EDIT: I assume I do not have to put `[Produces("text/csv")]` over every single action to force only that type, right?
