Multiple SubRoutes - is it possible?

[zam6ak]

Is it possible to have multi-level subroutes with this module?
For example

main router has
"reports/*subroute"
and 2 or more modules

1. "operational/*subroute"
2. "monthly/*subroute"

then , each of submodules defines its own set of routes.
That would make
/reports/operational/a-report
/reports/operational/b-report
where a-report and b-report are defined as final routes...

Or can only 1 level submodule be defined?
If multiple levels are possible, is there an example...
