I doubt it will ever be possible.

Back when I applied to college many years ago, IIRC all the colleges I applied to used Common App as mentioned in a sibling comment (I only applied to five top universities, no idea about the less competitive ones which constitute the majority), but each one had a distinct set of extra questions and/or short-form essays, and no amount of software could save you time on those. I even had to carefully customize the “common” personal statement in order to play to each recipient’s (perceived) interests.

I guess cookie cutter bulk applications could be used for fallback options, but those are not the time consuming ones in the first place.
