Reverse Engineering Tibco Data Virtualization

We have an issue where we are using TDV (Tibco Data Virtualization).  It uses a subset of SQL with some specific datatype changes and a physical path to the stored views of the data.  We need to model this as part of the data lineage.  It goes through multiple transforms and results in a normalized layer and eventually a denormalized business view.  It is important that we capture all of this.  Is there a way to create a custom language transform that allows the user to automatically reverse engineer based on the TDV language.  We have almost 4 years worth of data and hundreds of models.

Any direction other than do it all manually would be appreciated.
