Enforce subsystem order in the Model Heirarchy

Does anyone else recall being able to enforce model heirarchy in pre 2010 versions of simulink just via naming convnetion? For example you could numerically enforce order with a convention like this:

mdl - 1. subsystem1 - 2. subsytem2 - 2.1. child1 - 2.2. child2 - 3. subsystem3

In my latest simulink model, which uses 2013b it seems totally ignorant to the numbering, at a single level in the heirarchy I can have

mdl - subsystem 2 - 1 subsystem 1

or similar, no matter how hard I try I cannot get subsystem 1 to appear above that named subsytem 2. For prinitng and organisation of the model I always think it should be good to be able to enforce order of heirarchy at each level.

Does anyone know if this is possible or has been disabled?

I'm not sure I understand the question - by "order", do you mean execution order, or hierarchical order? If it is the latter, should just creating subsystems in the desired order be sufficient, why would you need to depend on a naming scheme?
