Author-Sort instead of Author in booklist

I wanted to change the book list column from 'Author' to 'Author Sort' so that it's 'Smith, John' instead of 'John Smith'

It sorts by last name, but to scan I find it easier to use if it's displayed LN, FN. Tag browser works, but I don't use it all the time

1. I thought that Author-Sort would be a selectable column, but couldn't find it. Doesn't seem to be too columns defined many that can just be added

2. I tried to add custom column, but got stuck on I thing the lookup-name part

I did try to find available lookup-names it in the manual, since I think that's what I need

Is there a tweak or a way to define a custom column that I'm missing to have it LN, FN?

Thanks

Edit - to clarify, it's not the tag browser since the tweak for that works fine; it's the book list grid
