Allow users to create personal views but not see other user's personal views

[highondefi]

Since personal views cannot be restricted to 1 user, I'm looking for a workaround.

I'd like our users to be able to create their own personal views based on a master table.

I don't want them to see anyone else's personal views (which AT currently doesn't allow).

I need to set up automations based on each user's personal views (so I don't believe we can use interfaces).

The solution I came up with was a master DB 1-way automatically syncing with multiple bases, but the problem there is the sync feature is unreliable. AT claims it's an "instant sync" but it is not. Many of the child bases do not get updated data for minutes or longer. 

I've been trying to find a solution for almost a week but haven't had any success.
