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

[VictorioBerra]

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?
