Is there a way to reverse an animation?

Hey, as the topic says, after making an animation, is there a way to make the animation go backwards in the sequence editor? I’m trying to make a soda can go from being crushed to whole and it would be MUCH less time consuming and complicated to make it crush and then reverse the animation.

time ipo!!!

you could even make the animation of one object stop, go backwards, resume at 3x before returning to normal speed…
