Can i view the custom properties created in Window Azure via signing in or without graph API

Hi,

I have a free window azure license and i am using Azure AD for authentication.

Now i want a custom property say "XYZ" in azure AD, My Questions are :

1. Can i create The Custom properties OOTB ?

2. How Can i mange them? Can i mange them from Azure interface or azure is providing any interface to manage them?

Thank You.
