Prevent Let'sEncrypt/SSL List to Be Obliterated Upon Error
I have multiple domains on a server/app (DO) that were typed before. Every time I add a new domain to the SSL list (after adding it in the Addon Domains list), I have to brace myself because a single typo or error (especially in a list with dozens of domains) will cause the entire SSL installation to fail and the SSL for all domains is removed. I'm aware a separate SSL is created for each domain, but you already have the multiple-domain list up and running, so if a new one is added and an error occurs, at leats don't let the entirety of the list be obliterated. If it's a Let'sEncrypt rule, at least keep a copy on-server that can be called, because there is no facility to do this, or even copy-paste the list.
I am thankful we're able to have multiple SSL certs on-server now, and I do understand Let'sEncrypt is a third party add-on you provide and whenever there is an addition of a domain to the SSL it generates a new SSL for each one. But I only suggest that when an error occurs, the system shouldn't obliterate the entire list of domains. Even if this is a rule of LE, at least leave a copy (or a way to save us from having to re-type everything manually each time, with multiple points of failure, so that even if a single character is mistyped, the entire list is removed and we have to type it all over again.
