You can provide additional document. Dont do replacement as they might put your application back for eligibility check. Additional document will help officer review in case officer has any concerns. Attach a word documebt with explanation letter as well. As it is recommended pass it is now in queue for officers review. If officer has any concerns your additional document will take care of that. This is just my opinion.so does the replacement, sets back the application as it has to go thru review again?
