changing GM Records

[NYG]

Under 'Globe Game Options' you can view general manager records.
It gives you the option to delete all records.
does anyone know how to delete selective ones?

I'd like to keep my current SP league records there, but my previous ones were tests etc and are not necessary anymore.

Where is it reading this information from?
In my 'Universe' folder I dont see any files that relate to these older leagues I had done.

thanks

I haven't looked into this at all, nor have I seen anyone here post that they have. My guess is that there's no easy way to do this, sorry.
