A Quaestio on the Ordo of the Supplementum of the Tertia pars

Below is a query passed on to us by a friend of thomistica.net:

A friend of mine is finishing her dissertation on marriage in Aquinas and, obviously, has drawn heavily on the Scriptum on the Fourth Book of the Sentences. She is wondering if anyone has done any detailed work on how the Supplement was fashioned by Reginald et alia. Does anyone know where they got their plan of questions and articles? Is there any indication that Thomas left a framework beyond the prologues that outline the content?

If any thomistica.net readers are aware of any work done on the question of the ordo of the Supplementum, please respond by posting a comment.

Valete,
