Might I ASSume you are talking about specifically your shotguns? Maybe more specifically your wife's?
Not tool-less but these are common in target sports:

And these are available, but only for Remington:

But to answer your question, AFAIK it is not a thing. If you are asking because your wife might like to try a shorter stock, you can make it shorter and add back spacers if you go too far. If you are asking because a friend or family member might want to try shooting and borrow your gun and you borrow it back for the next station, I dunno of anything out there.
