How to format numbers with custom labels (metric) after them


I am trying to show multiple KPIs with single value visualization. How do I format the number and add miles, hours, days, nights etc. after the value? I would like to display something like:

1,029 miles
Avg. Distance Traveled

I am trying to avoid having to create custom string fields converted from a numeric value, so ideally would just like add the label (miles) at format option:

,d “miles”

The issue with creating a custom text field instead of
a) it makes the tables cumbersome, having to add a ton of unnecessary fields
b) have to apply custom text formatting on the numeric field itself (ie thousand separators)

So I would like to avoid doing using a custom field and just address this at formatting.

Thank you,
