You can nest blocks within blocks to create extra efficiencies.
Some examples of when you might want to nest blocks:
The same floor plan is used on multiple levels within a building (nest the floor plan block into the building block)
Same town house plan can be used in different configurations (duplex, triplex, quad, etc)
The same bathroom plan is used in all of your apartment unit layouts
To nest a block, simply create a block with a block as part of the selection.
Block instances update when the definition is updated whether they are nested or not.
