In-between targets in blend shapes missing

Hi, does anyone know how to import in-between targets in blend shape animations from Maya 2018 to Unreal engine 4 (as fbx files)? I got the blend shapes and they are working fine, but since the in-between targets got omitted when imported, the animation is clipping. Is there a way to import them? Or perhaps there is some way to adjust them in engine? :slight_smile:
