Request: Third-Party SSL Certificates

Feature Request|We are collecting votes for this issue
Currently, Wix does not support third-party SSL certificates. All Wix sites are enabled with HTTPS, so are created with inbuilt SSL certification. We do not authenticate sites built elsewhere. Therefore, we are unable to generate CSR files (SSL authentication) for domains and subdomains connected to external sites. 
We are always working to update and improve our products, and your feedback is hugely appreciated.
