Subclip Sorting Issue - Documentary Transcription

Urgent subclip question.

I'm editing a feature documentary with hours and hours of interviews.  We had an assistant editor transcribe all the interviews using sub-clips (as you would in Avid and as an Adobe tech suggested when I was considering using markers instead).  The assist put the word for word transcription in the "Name" metadata column of the subclips and the shooting locations in the "Scene" metadata column.  We planned to then use the "Creation Date" metadata to sort the subclips by shooting order so each transcribed line would be listed chronologically in the bin.

However, the creation date gives only the time when the record button was hit, not the timecode as it was running.  Some of the interviews are single hour takes that we've divided into hundreds of subclips, so obviously that creates a massive problem.  If I was using Avid I'd just sort the clips using multiple metadata columns (Creation Date, Media Start, Scene... in this case), but technical support said Premiere doesn't have this capability.

The ability to sort subclips by the order in which they were shot seems like very basic functionality and essential for longform doc editing.  There has to be a simple solution to this.  What am I missing?
