How to import multiple meshes with parameters in one element from Maya ? (Not Max!)

Hello everyone I want to import my example “Door” mesh which is simple has one outer part and inline door part outer part is static and inline door will have parameter of rotating to open it by expected amount. I want to import these two in one element without creating second mesh file how can I achieve this ?

I’m not sure how it is in Maya, but in Max you would need to Link the moving part to the non-moving part (so the non-moving part would be the Parent to the moving part) and then import it as a Skeletal mesh in UE4. So that will mean that the meshes are like a rig but without using bones.
