The next update should include batch rendering for panoramas! 
My apologies about the last reply in case you’ve read it a couple of days ago - We actually already support Batch Rendering for Panoramas, just only in our preview of Enscape 3.2 so far. This functionality will of course also find its way into the full 3.2 release soon.
In the meantime, feel free to give our latest preview a try, and if you get the chance to, then in order to batch export multiple panoramas at once simply make sure you have multiple views (at least two) available/created, click the “Batch Render” button and select whichever views you like:
Afterwards simply press the little arrow key next to “Render Images” and batch export your selected views as either mono or stereo panoramas.
Please feel free to also share any additional Feedback with us regarding this functionality, the preview, or Enscape itself if you like.
