Question Let's Encrypt for ONLY alias domain?

HostaHost

Regular Pleskian
Anyone know a way to work around Plesk trying to get an LE cert issued for both the primary domain and the alias? For a website under development, the primary site may be pointed elsewhere, but it needs to be defined in Plesk with the real domain so the paths, email addresses, etc. are all correct. We'd like to have an LE cert issued for just the alias domain to allow development to be secure, before switching to the primary domain later on.
 
Unfortunately that doesn't work. The issue is that while that does allow you to have an LE cert issued to an alias, it attempts to order the certificate for the primary domain first with the alias as an alternate name, so when the primary fails (because it isn't pointed at the development site), the alias fails too.
