Is there a way to filter the responses?

[nbro10]

Often, we don't need all info from a response. For example, if we query an ad, maybe we just need the campaign ID associated with it and maybe the name. Is there a way to to automatically ask only for the info that we need? The documentation mentions filters here, but I don't know if these are related to my needs. I didn't find any example so far that uses filters anyway.
