Roscolux R368 missing from color picker

There was another thread in this forum from a few years ago but it was never answered or resolved - the Roscolux R368 Winkler Blue gel seems to be missing from the color picker in EOS (3.0.2.6). I've looked in all Rosco pages including "Other." Just wondering if there's a way for this one to be added - thanks!
