I have common use case where I allow content editors to customize the url-safe title of a piece of content. So, I might have fields like this:

The generated page here would be found at /example/; if the slug field was left blank it would be found at /an-example-post-with-a-long-title/.

The challenge here arises when configuring the collection's preview path; I can specify that the preview path should include {{fields.title}} or {{fields.slug}} but I can't get it to follow the logic of falling back to title if slug is empty. This would be a fantastic enhancement. Maybe there's already a way to do this but I haven't figured it out. Thanks in advance!
