Custom HRTF in UE4


I am wanting to run some experiments with custom HRTF’s in UE4 I am aware that the SOFA files capability was added to Unity version of the Steam audio plug-in with steam stating they planned to add it to UE4. I am wanting to know if it is possible to conduct a HRTF shoot-out in UE4 with current plugins or out of the box spatialisation tools or whether or not I would need to dig into the code to be able to add custom HRTF’s?.
