Sub-Systems ?

I just started to play with the app (which is really good) but can't find a way to use a sub-system in another system. Is it a limitation ? Do you plan to do something for this ?

Thanks !

No file, test, or entry point is named. Start by tracing how the app represents and opens systems and sub-systems, then determine whether nesting is supported; done requires a maintainer decision on the limitation or request and a clearly scoped follow-up.
