Importing Historical Automatic Data for Older Vehicles

I was an Automatic user for many years and I have Automatic data exports for three cars.  One of those cars I no longer have, so my partner and I have just two Bouncie adapters for our two current cars.

Is there any way to add a 'vehicle' to the Bouncie dashboard that *isn't* tied to an adapter?  I'd love to be able to import the Automatic data for our older vehicle so it's data is in a more... usable form than just a CSV file.  That way, all of our cars histories (and tagged trips) can all be in one place in case they ever need to be referenced for any reason. 

These log files are essential our mileage logs for the IRS, so having it all stored 'together' instead of separately would be nice :)
