iCloud CloudKit, multiple Locations possible (iCloud accounts)?

It would be useful if I could establish more than one iCloud CloudKit connection for syncing databases. Perhaps one can and I don’t know how to do so. If not possible, will it ever be possible? For example; it would be handy for me to sync personal files with one iCloud account and business files with another. Thanks, Scott. (New Hampshire, US)

My understanding is Apple allows only one account logged in at a time. You can achieve this if you use multiple third party cloud service providers.

No, this is not possible. An Apple ID is meant for personal use so you can’t sync across accounts.
