Backfill change property event history from property change history

The goal would be to enable backfill of a property change event from the exported change history of said property (currently accessible via “export property history”).
I do not wish to correct any errors in the property but rather to get a richer insight on historical changes of said property based on the existing data. Activating “Track changes” only gives change data from that moment onwards but it would be useful to insert the previously accumulated change data from the export, right from the moment one realizes he/she needs said change data.

It would be beneficial to do this directly in Hubspot as then the historical change data could be used in reports and dashboards and, thus, easily shareable with other stakeholders.
