Yes, the solution my colleague Victor suggested in the thread below is applicable. Additionally, you can download a sample from this blog post
. In order to extend the sample to the news widget you need to change the type of widget used for your field from the definition. The UI for creating a custom field doesn't let you do that, but you can go to Administration -> Settings -> Advanced -> News -> Controls -> NewsBackend -> Views -> NewsBackend Edit -> Sections -> CustomFieldsSection -> Fields ->[Name of your field].
