How to specify a different parent directory when loading backed up `ResultGrid` objects?

When running experiments I save to a local nvme storage volume.
However, to save space, I move my checkpoints to storage array afterward.
I have found that loading a ResultGrid object from a different location e.g. /storage_pool/my_backed_up_experiments/results.pkl tries to find various checkpoints and checkpoint-adjacent data at their original absolute paths.
