Full List CSV export feedback

Community Champion
  1. When clicking Missing submissions or Late submissions from the assignment details box, I get the option for the Full List CSV. This Export does not contain any info in the "SIS User ID / Email Address" column.  Is this just because it's in Beta instance, or is this a bug? 
  2. The "Canvas ID" column seems kind of useless to instructors when reviewing this list. The underlying ID really means very little to them in general. The student ID (SIS ID in our case) or the email address seems more useful to help with telling two people of the same name apart from one another.
