Sort Records by Field is a quick-n-easy way to sort records by a single field. That's it. No more. All it does is save you a few steps when you have very simple sort requirements.
Sounds like a good Product Idea.
Given the user point and click options for specifying a variety of multiple field sort orders for the same scripted report is especially tedious.
"add to sort" option would be nice...
add sort by field to sort would be even nicer
