ORMLite has been developed by Brian Christensen and others.
Since I was not a member of the original development team, I don't know the answer to your specific question.
However, ORMLite is open source and is written in Python which means that if you know Python then you can add your own components.
So how to you get to grips with Python?
One way is to take the free online 9 week course in Python that is due to start on 15 April 2013.
The estimated workload is 7-9 hours per week.
The course is hosted on Coursera and is run by Professors Scott Rixner and Joe Warren of Rice University, Houston.
