AFAIK, the OP wants to skip Emacs asking for the preferred format and
instead let her choose a specific format if already present.  The goal
here is to keep the chit-chat with Emacs to a minimum which I understand
since I initially wrote the yank-media code for Org to keep manual
intervention to a minimum when linking to images, etc.
