Audio link doesn’t work when more than one passage is provided.

If I provide more than one Bible passage in a bible reading post under the “Bible Passage” field, the button to read the passage works great. I am able to read the entire set of passages in one flowing page.

However, if I click on the Audio link, the player defaults to Genesis chapter 1 because (I’m guessing) Bible Gateway doesn’t support more than one passage when visiting their audio end point.

Am I simply inputting them incorrectly or is this a limitation of the API that Bible Gateway provides? I guess I was envisioning something like ESV.org’s API where you can queue up several passages:
