Default view of empty RM fields?


Active member
I would like to add an additional field to one of my resource manager categories (category_1). The field name is "bio" and should appear in a new tab "Bio". The content of this tab is retrieved from a template callback.

What I found out now is that I have to edit every existing resource item in category_1 and enter a value in field "bio", otherwise the tab "bio" is hidden. Of course this makes sense in general, but in my case it would be very helpful if I could find another solution to view this additional tab. Any ideas?
