sound cue export/ import publishing

Hello, Im soon to be launching sound samples on the marketplace, however the terms state all WAV files must come with a corresponding sound cue file. Now I have created sound cues of the wavs in UE4 and exported them, but you cannot re-import these sound cues back into the engine, there seems no way of exporting and importing ‘any’ sound cue into the engine. Do unreal make these files adaptable once submitted so that when purchased they become a usable sound cue ?

You are probably misunderstanding how to publish marketplace assets.
You do NOT export the assets you made in the unreal engine, you Zip Up the complete Project and send that zip to epic games.

Yes, im aware of that, your misunderstanding me, I obviously had to create sound cues in UE first.
