savegame – Unity – Save and load “Snapshots” of game for debugging?

I’m relatively new to Unity debugging, and I’ve got an issue that happens every so often about 2 minutes into playing through a scene. If I can do the following, it would save me a lot of time debugging:

1. Pause the scene
2. Save the snapshot
3. Modify some code
4. Play the snapshot saved in step 2
5. Repeat 3-4

Is this at all possible with Unity, or should I just modify my code to running “closer” to the point I’m trying to debug?
