Checklist Item History

We'd ideally like to be able to see a record of past checklist item completions. At the moment, if a volunteer's training expires and we re-train them, we can update their checklist item with the dates of the latest training, but that then removes any record of earlier training. We still need to have a record of that so that if there are any issues or concerns raised about past shifts, we can still check that everyone was appropriately trained.

As such, it would be good if you could see previous checklist item history.
