Meathod to increase amount of custom outfits?

[SirSquill 0]

Hello all I’m currently seeking out a method to increase the amount of custom outfits in single player. 
 

I’ve tried the custom outfit changer mod, but it appears those outfits don’t function in terms of temperature protection. They seem to just paint over whatver existing clothes you’re wearing. 
 

I don’t really need any of the functions of that mod I’m purely looking to be able to save more outfits in the normal menu. Any guidance or help would be appreciated.
