Can QSys recurse through custom component, to generate IP?

I have a custom QSys component, that instantiates a couple of Altera IP. The Altera IP is also in the form of .qsys files. Is it possible to have Qsys recurse through my custom component and generate the instantiated IP for me? Currently I have to open each IP separately and generate it, only then does the component synthesize properly?

Qsys distinguishes between components (defined by a .tcl file), and subsystems (defined by a .qsys file). It looks like you want to use subsystems.

The procedure for adding either of them is basically the same though. Add the path where you store the components or subsystems to the IP search path in Qsys preferences. After you refresh the system those components and/or subsystems should appear in the component list, and you can instantiate them like with the built-in components. Subsystems should show up in the Project -> System group in the component tree. When you generate the system, the subsystems will be generated as well.

While this is how it's supposed to work, there are various bugs in different Quartus versions that can give you some problems. The easiest and safest way is to keep all the .qsys files (both the top system and the subsystems) in the directory of your Quartus project, and launch Qsys from Quartus when your project is already open.
