Fuel import expenses

We are spending far too much time putting in fuel.
We get a CSV report from our fuel card as well as from our on lot fuel tanks there is a field in these reports i get for trip number. You should be able to write an import that will utilize this field and put fuel expenses into the appropriate trips. without this function ability the fuel import is not worth using for me. I need to be able to expense the fuel to each trip so i can see profit and loss for each trip.
