Space referencing is the ability to create a Space within Project using that Spaces programming and UI layout. No additional programming is necessary and gateways can be configured within the Manager for the referenced space as this would be the only item necessary to change.
NOTE Accessing the Builder to change layout is not possible for a referenced space. You would have to detach the space and use the space as non-referenced to make UI changes.
Select existing Project from Left Pane
From Menu in center pane choose the option to Add New Space
Within popup window, Add Name/Description and Select the Option to make this Space a Reference
A new Menu appears, choose the Space to be referenced from this dropdown
