Stockfish as opponent in an already finished game

So, is it possible to use Stockfish as an opponent after a normal game ends (player vs player) to see how you would fare against a computer in some position in a finished game? I'm not meaning the analysis board but the possibility to start playing a computer in position in an already finished game. Could this feature be implemented or is it already?

If it's a position where more moves could be played (i.e game did not end in checkmate), you can copy the FEN and play against stockfish like so.

The practice with a computer feature might do what you want. It doesn't start a new game, but it'll allow you to practice against the computer from the current situation.
