Dashboard Column for Total Social Security

[Tara]

I want to add total social security for my clients (taxpayer and spouse, if there is a spouse.) But I can't see that as an available column in the Dashboard available columns to view. 

Am I missing it in the list or is it not available? If it's not available is there a way to add it?

Thanks!

I dont see it as an option.   You wouldnt be able to add it, that would be a programming change.
