Can I sync Notes to and from a secondary iCloud account? I have my work iCloud account that needs to be primary for Keynote collaboration etc. 

But all most Notes are in my personal iCloud account. I can use my personal iCloud account for iMessages and iTunes, is there a way to also use my personal iCloud account for notes? 

Did a bit of searching and found this answer - Notes from iCloud account don&#39;t sync with devices when added as secondary account - that is a bit confusing with the various upgrades downgrades of OS. I am on all the latest OS versions.
As of now, it is not possible. I tried adding a secondary iCloud account in Notes>Accounts and Apple restricts the sync of Notes, etc and only supports Mail, Contacts, Calendars, and Reminders on secondary iCloud accounts:
