Initialize ledger-records on pre-existing model-data

I'd like to use Accountant for a project where i already have existing data in a database. After installing Accountant, it correctly detects the "update" event and writes a new record of my Model into the ledger. Problem is that i loose the initial data, because the "created" event was not recorded and the updated event record only saves the new state.

Is there a way to initialize a record for all pre-existing data/properties? ...basically adding a "created" record to the ledger for each model instance that already exists?

Or is there a way to automatically add a record with the original data/properties, the moment an updated event is detected but no previous records for that model are found in the ledger.
