Out of curiosity, I decided to decide whether it was possible to retroactively create a challenge for a previous year.

My steps;

1. Take a backup of the JSON.

2. In challenges_dict, duplicate this year's "Books Purchased in 2024" challenge. I then edited the name, timestamps, and reset count and progress:

        "Books Purchased in 2023": {
          "count": 0,
          "end": {
            "__class__": "datetime.datetime",
            "__value__": "2023-12-31T04:00:00+00:00"
          },
          "progress": 0,
          "start": {
            "__class__": "datetime.datetime",
            "__value__": "2023-01-01T04:00:00+00:00"
          }
        },

3. Check the "custom challenges" dialog to make sure the newly-created challenge appeared.

4. Go to a book from 2023's goal, and edited it:

      "challenges": [
        "Annual",
        "Books Purchased in 2023"
      ],

However, here is where I got stuck. I expected the 'count' and 'progress' to automatically update itself; it didn't, so I edited them to 1 and 100. When I next opened Edit Goal, it reset both back to 0 and the challenge appeared for the current year (with no books):



I've just reverted to my backup, but I'm curious whether I missed something here that could've made it work.
