SQAN: option for multiple deletion on exams view

[jcf2]

Feature request:
The exams view can sometimes contain unnecessary entries (e.g. I have 24 PhoenixZIPReport entries that were picked up during ingestion). There is an option to Delete Exam, but this requires action on each separately, with entry of a reason for deletion. It would be great to be able to delete multiple entries in one action (e.g. use selection boxes and then "delete selected"?).
