How do i create a NPC appearance mod that also changes the body?

[Rand4ll]

So, after changing the NPC looks with slm for a while, i decided to try to make a mod that does these changes for me, like Loving Curie, Piper and Cait, and i did it, i used face ripper to turn my preset into a mod that changes Cait's face, but i have added some tattos on her body with the Looks Menu Body Tattoos and i don't know how to turn it into a mod. I've seen some mods on nexus that does exactly this, like Dread Cait Overhaul that have some tattoos from the same mod i used, anyone can help me?
