The first name listed is typically but not always the first name that was added. All the other domain names for the site will also be included in the SSL certificate, but only one name can be the primary name for an SSL certificate.
Here is the information for this site’s certificate:
$ echo | openssl s_client -showcerts -servername staging-play.cinesend.com -connect staging-play.cinesend.com:443 | openssl x509 -text | egrep '(Subject:|DNS:)'
depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
depth=0 CN = develop-play.cinesend.com

There isn’t a way to change this order at Netlify. You might be able to get a different order if you manually provision your own SSL certificates or purchase SSL certificates from a third-party.
We can enter a feature request to control the order but no such feature request exists at this time.
Please let us know if we should file a feature request for this. Also, if so, would you please explain more about the reason for wanting to make this change? We ask because we want to be sure the feature request meets the requirements you have. The more we understand about the why the change is needed the more it will help us to build a feature that works as you want it to.
If there are other questions for us, please include them at any time.
