Anyone who wants to "mass add" graemlins, here's a small script that might help.
https://www.ubbdev.com/ubb/upload/00020028/graemlins.txt Save as graemlins.cgi and upload to your cgi-bin. CHMOD 755 and run it from your browser.
It will scan your graemlins directory and output a page that will show exactly what you need to add to your vars_graemlins.cgi to have them all added. (Copy/Paste, I haven't been able to get it to write to the file itself.)
Keep in mind that this work could be undone if you have more graemlins in your noncgi/graemlins folder than the allowed limit (this mod makes it 250, so there shouldn't be any worries).
Once you updates your vars_graemlins.cgi, upload it and you can edit the graemlin settings in your CP
