[Bulk Edit module] populate an empty property

With the Bulk Edit module, how can I populate a property which is empty in the first place? If I use ‘Replace literal values’ and then leave the ‘String to replace empty’ and add my string in the ‘By’ field and submit the form the changes are not applied. I suppose it’s because the property is empty in the first place. Is what I want to do possible with Bulk Edit?

Apologies, I just noticed the ‘Add text value’ at the bottom of the page in simple edit mode.
