Field Transformation Rules to Match Contextual Filter Transformation

Currently, Contextual Filters support transformation to lowercase, and replacing spaces with dashes. Using something like Title, this is a common filter to apply. It seems that there is no native way to apply the same transformation to Fields.

Is this for a specific reason, or has this been covered in a patch that hasn't been committed to the current repo? I use views_php for this currently, but I figure this would be super helpful to be in Views.

Thanks!
