Feature request: Automated PrintFriendly attachment

I use Paperpile to keep track of articles on web magazines and such, but I like to keep a plain-text (i.e. no images) PDF copy attached to the entries I generate in case there is the possibility of losing the article. I use PrintFriendly to do this. It would be really cool if there could be an automated way to attach a PrintFriendly formatted PDF to each entry I generate, sort of like the already existing “Auto-Update” feature.
