问题
I receive data in a CSV (kind of) format, in which each entity is represented by multiple sections of different record groups. In this fictitious example (below) I represent a number of colleges (the entities) by a number of sections of different record groups (these can be thought of as the tables). I have no control over the format of this incoming data. So I was wondering, when issueing a query on incoming CSV data using the H2 Database engine, can you somehow specify which line to begin at based on some kind of pattern to identify the first line of each table for a given entity? The fictitious data is below.

Currently this is not possible out of the box. The data would need to be pre-processed (split into multiple files).
