CSV Rating File for IRC or other TCF classes

I'm trying to use a CSV rating file to publish an official list of
IRC-certificates and similarly a list of national Cruiser Racing
Class handicaps, for use with Sailwave.

The typical CSV rating file has just three compulsory fields :
System, Class, DefaultValue, this last is the TCF (or IRC TCC). A
fourth field is optional, used for multiple coefficients.

In my databases, all IRC and CRC yachts have individual ratings.
A first attempt was successful, but I had to enter each boat with my
SailNumber + BoatName fields as Class.
Furthermore there is no place to enter the Group (ex IRC 1-2) or a
BoatType field.
And "my" Class field is 42 characters long.

So for me the IRC / IRM systems are not very usefull

Solutions (existing, but hidden?):
* extend the use of the CSV rating files with subsequent fields
SailNumber, BoatName, BoatType, Comments (used to display info, like
certificate unpaid, or equipment restrictions)
* use anoter CSV file, in another folder (but ratings/ is so
convenient...)
