Adding an Additional Option on Nested Tags (Hierarchy)

On Nested Tags/pages if i have something like [[test/one/two/three]] it would be nice to be able to go to one of those pages (like test/one) and create a new page just by typing [[/new page]] where that would now be nested under test/one as test/one/new page. Is that possible or do I need to do a feature request for that?
