Reuse training data with different field names

[jdarling]

Is there a way to reuse training data when the field names change, even it it requires mucking with the training data file?

Example I run a training set on a file with field names; firstname, lastname, email.

I want to use the same set on a different file with field names; first_name, last_name, e-mail.

The "rules" are the same just the field names are different.
