Create a task/template to rename a PDF file upon initial CheckIn

Good afternoon. I am trying to figure out a way to create a task/template/card, and whatever else is needed to allow for renaming scanned files upon initial checkin.  For example, I want to be able to check in a default scanned document with name "newscan", and be able to rename the file to "partnumber"_LOT"lotnumber"_PO"ponumber"_"dropdownlist".pdf

The dropdown list is created on the data card.

Is this possible?  Am I clear as mud?
