Overwriting/Replacing A Checkpoint's Function?

[SonOfLiberty796]

After a bit of testing on my side, it would seem CheckPoint only applies a start position and callback to the checkpoint name if the checkpoint hasn't been set at a previous time. In other words, you have to give a unique checkpoint name to each checkpoint.

So it has to be like "CheckPoint1" and "CheckPoint2"? Like different names for each checkpoint?
