Use View Properties on a presentation sheet viewport
Switch a viewport to another saved view, open a view in the design, and unlock a view that is on a sheet.
In a presentation sheet, a selected viewport's View Properties show a view selector (switching the viewport to another saved view) and an Enter View icon that opens that view in the design.
A locked view shows a red 'View is locked' label at the top (tooltip 'Unlock from views bottom bar').
Unlocking a view that is on a sheet asks 'Modifications to <view> will affect the sheets linked to this view in presentation. Do you want to proceed?'
