Register custom race spell help

[pana8inaikos]

Hi all.

I used to have sexlab framework light se, and i had a spell :register custom race, so if some custom followers that i have downloaded ,was custom race, if i used the spell i could trigger sex scenes.

(before the spell , a message: (name of npc) appears to be not human, poped up)
I switch to SexLabFrameworkSE_v163_BETA8  and there is no such spell, is missing.There is a way to retrieve the spell?
