Conforming Hair cards to metahumans

Is there a way to conform user made hair card meshes to metahumans? The Hair card meshes included with metahuman creator are somehow conformed to the metahumans, but I cant figure out how to use that same system for custom made hair cards. The metahumans include various bones that seem like they are used for conforming hair to the head (FACIAL_R_Sideburn, etc.) but the hair assets imported into unreal are all static meshes, so I’m a little confused.
