How to reverse a quick explode animation in blender, without rendering it and reversing the video

There are other animations happening in the scene at the same time as that of quick explode. So, I can’t reverse the video. Also, I can’t find any option of “bake to keyframes”.

Need to see something…have no idea without something to look at…
a couple shots of the timeline and action editor…

it may be possible inside the action editor…copy and reverse paste selected keyframes…
