I am afraid there is no such filter now, a value has to be specified for the field. It's unlikely we would implement a UI for this as this would complicate the filter form considerably, having "not empty" checkbox next to each field, but we could definitely implement a URL support. We will update here once we have a solution for it. We should be able to provide an update in the coming week.Come to think of it, I don't even care about the UI for this - I really only care about creating a URL string that I can link to for a filtered list within an SC category. The only requirement is that the string needs to be able to limit the list to items where a specified field is not empty. Maybe your add-on already allows for this? If so, I'll buy it as soon as I can get your website to load.
Thank you!
