Help with Chess.com chess engine

I've looked through the site and couldn't find the answer to this question.

When I analyze a game with chess.com, it shows what the best move was, and the line following that.

Is there any way to get the engine to show what the best line to DEFEAT my move would have been? (or the opponents) Or why my move was bad?

Often, I am left looking at what the best move was...but can't discern why my move was an inaccuracy, mistake, or blunder.

The engine, to my knowledge, only shows why the best move was the best and how to play it. It doesn't show why my move was weak, or how my opponent could exploit my move. Granted, sometimes it's obvious (I'm a ~1200 player and still hang pieces) but more often than not I'm totally befuddled. 

If this is in the wrong section, please advise where it belongs. I'm not much of a forum cat.
