I accidently recorded a work trip under wife's car how can I change the vehicle?

I started a trip log and went to a job but on my return when I finished the trip I went to look at it but could not find it. Turns out I had started it under my wife's car I also track in fuelio. I would like to edit the trip to have it reflect under my vehicle, is that possible or only a manual entry and deletion under wife's?  Thanks!
