changing name of ingame infant carrier

hi all,

i'm trying to make recolors of the growing together infant carriers.. i've overrided them and recoloured them for when you are using them BUT i haven't figured out how to change the ingame thumbnail or id for them..

for example, it shows up in the "set preferred baby carrier" menu as " infant wrangler white and pink " 

any help would be appreicated, thank you
