Code split sub-routes together
Wondering if it's possible to control how lazy file-based routes are split out instead of having each route be in its own chunk. Potential desired behavior would be that everything below a certain path (e.g. /users would include /users, /users/1, /users/new, etc) would all be included in the same chunk so that once you "entered" that section of the site once you'd already have the rest of the code loaded.
