I currently have a data indicator in a dashboard that is formatted to sum the values in a specific field and show an indicator like the below:

The data being pulled for this indicator currently has no records, and by default the "no data" text appears in the indicator box. As far as I can tell, there is no way to format the "no-data" text to appear exactly like the above indicator but with a 0 in it's place.
I've tried editing the arcade script for the indicator with both IfEmtpy statements or if $datapoint.sum_FIRE_Size <0 (or is Null) return "0" but I can't get my indicator to display a 0 in place of the no-data text.
Any ideas on how to solve this? It seems silly that the formatting for the no data doesn't have the same customization options as the actual indicator.
