I don't think this is available using the Layout tool.
You can do something like this by adding "Windows"
Is it possible to customize a view layout as below? Thanks!
There is no exact OOTB layout available under Menu > View > Layout > New or Open.
As shown by @joycejo , same you can achieve using 'Aero Snap' functionality that has been introduced in NX 11.
See this video for clear understanding.
However, in NX12, the same layout is available under 'Window Layout' only (Not under Menu > View > Layout > New/Open) as shown. But again, it is the same as snapping multiple windows just like aero snap function in NX 11. It only saves some mouse clicks.
