Unable to paste a list of email addresses in New experience, as with Classic experience

With the Classic Adobe Sign gui, one could select 'sign in any order', then paste a list of comma-separated email addresses in the first address field, and Adobe Sign would parse those out to individual recipients, in the order they were provided.

In the "new" experience, pasting in a list of email addresses results in an error. I see no way to bulk-load a list of recipients.  

Is there a workaround I'm not discovering on my own?  Adding recipients (our entire Board of Directors) one name at a time will add greatly to my workload on each file sent for signature, as compared to the Classic experience.

For now, I'm reverting to the Classic experience, but I fear (perhaps not validly!) that it will be deprecated in the future.
