Paper Trail saving virtual attribute changes within object_changes

Question

I am trying to persist virtual attribute changes within object_changes and have been working with the meta option.

has_paper_trail(
  meta: {
    status_name: proc { |foo| foo.status&.name }
  }
)

I added status_name to the versions table as the docs mention, and that attribute does get persisted. However, instead of being saved within the object_changes hash, it is in its separate column, and the value does not include the previous value.

# version attributes:
object_changes:
  "{\"updated_at\":[\"2023-01-18T22:50:22.394Z\",\"2023-01-18T22:50:22.408Z\"],\"status_id\":[1,2]}",
 status_name: "Status 2"

This is working as the gem intends, but I'd like to push the status_name changes into object_changes and include the previous value. One way I've been able to get the before and after changes stored is by creating a new method using the meta flag. But it seems clunky, and I'm wondering if anyone has an alternative:

has_paper_trail(
    meta: {
      status_name: :track_status_name_changes
    }
  )

  def track_status_name_changes
    if versions.blank?
      [nil, status&.name].to_json # "[null,\"Status 1\"]"
    else
      prev_name = JSON.parse(versions.last.status_name).last
      [prev_name, status&.name].to_json # "[\"Status 1\",\"Status 2\"]"
    end
  end

I'm currently exploring creating my own adapter like mentioned in the docs:

PaperTrail.config.object_changes_adapter = MyObjectChangesAdapter.new

class MyObjectChangesAdapter
  # @param changes Hash
  # @return Hash
  def diff(changes)
    # ...
  end
end

Going with the custom method in the meta flag I am able to track the changes of the virtual attribute, however, I'd also like to have those changes stored in the object_changes column of the versions table.
