Multiple SSL certifcates on single site with multiple domains

Hi, We are looking to install multiple SSL certificates on a site with multiple domains, This would potentially include a mix of wildcard, OV/EV and unique subdomain certificates. However the Netlify portal under HTTPS only allows one certificate to be installed and used at one time, despite additional domains being configured for the site. Could someone please advise if multiple SSL certificates can be installed and configured for each domain and subdomain? The documentation doesn’t seem to …

Each site can only have one certificate. You would need to do either of the following:

1. get a certificate that contains both domains, which may be a challenge even if you own or have administrative control of both domains
2. create a second site for the second set of hostnames. You may link a second site to the same repo to create an identical build, though you will need to duplicate all settings onto that second site.
