Security rules and Custom property

[DinShor]

Hello everyone,

I have serval problemns with securty rules based on custom property:

1. I want to give user option to assigned only some values in custom property, for example :
Custom property name: "Team" , and "Team" values are "Team1", "Team2" and "Team3".
"User1" has the custom property "Team1".
I want user "User1" only see and assigned the "Team" value "Team1".

2. I want set option that when I duplicate app, the duplicate app will get also the custom properties the original app have.

3. I need to give user the option to edit another user custom property but not to able block or unblock this user.

thank you.
