Wish Add Immersive Mode in Activity Attributes

[Sagenut]

Hi!
I think it could be useful to have the chance to enable Immersive Mode directly from Region Activity Attributes.
I was thinking to something like this:

#Region  Activity Attributes 
    #FullScreen: True           (other options: False, Immersive)
    #IncludeTitle: True
#End Region

or maybe

#Region  Activity Attributes 
    #FullScreen: False
    #IncludeTitle: True
    #ImmersiveMode: True            (other option: False)
#End Region

Nothing revolutionary but probably it could be a nice thing.
Or even better having the chance to activate and deactivate it with something like

Activity.ImmersiveMode(True)
Activity.ImmersiveMode(False)

Thanks for Your attention.
Have a Nice Day.
