Custom View Formatting: How to use a custom message when there are no items in doclib

Hello,

I'm using a simple JSON to create a nice view for our users on a doclib.
However when there are no items in the library, I would like to set my own custom message for the users to indicate that currently there are no items.(now we just get some icon that asks to drag items here)

Is this possible?
