[Feature Request] Separate the GUI theme setting out to per admin login

Dear team,

We have multiple admins in our IT team that logs in to the FortiGate on a daily bases, however, some of our team has recently discovered that they can change the theme inside the settings section, some of them has messed with the bright UI, and it is burning my iris.

Therefore, is there any possibilities that you can separate this to per login rather than a global config that applies to everyone once set please?

Appreciated and regards
