[Feature] `#volume-2`: Box for current block and the next one exclusively

[duiliuliu]

Are you considering implementing a feature where adding #volume-2 would only affect the current block and the next block, rather than their children? This would provide more granular control over the styling and layout, allowing for a cleaner and more organized document structure.

Hello! This is cool idea! However I don't have plans to add it now. But will keep this task open.
