Thanks for the suggestion but that helps for adding Checkpoints to the script. Editing it would be the same as if I changed the value in Expert view so I am still not able to modify the checkpoint itself in the object repository's "Checkpoint and Output Objects" section.
I have discovered that another way of adding a checkpoint is through Insert menu and then selecting Checkpoint from there.
