Sorry to hear that. As a standard process, I over comply with the various document requirements I attached PR Card Copy, Passport Copy and Driving License Copy (both sides). The checklist also clearly states the below :
- Photocopy of 2 Pieces of Identify Documents ( See the Checklist below)

When you submit, attach a copy of the letter they sent to you with your application. Also, mention on the top of the envelope "additional request for documents". I do not think they will process your AOR faster than the usual timeline, but there is no harm in trying.
