Some controls have a 'teach mode' that records your jogs. You can then replay the jogs either forwards or backwards. This is pretty much the same as you describe. Things get a bit more complicated when you are using MPG jogging, especially if you have multiple MPGs. In that case all you can do is record the machine position at regular intervals then join the dots to replay the moves. However with modern computers, storage space is not a problem so you can store a virtually unlimited number of moves.
