Safe Area Guides in Fusion

I'm surprised to find that I can't easily turn on Safe Area Guides so that I can ensure that text and graphics are within the Action Safe and Title Safe regions. I go to View and down to Safe Area and it is all greyed out. This would be incredibly helpful to have. Please enable this in a future beta update.

Safe area guides need an overhaul in general, far too limited at the moment. There's more than one text safe region depending on where you are delivering, for example, and this really needs to be customisable.
