MATLAB: How to copy contents from one Subsystem into a sub subsystem within another model

add_blockr2013bsubsystem

Hello, I am trying to copy a subsystem from one model into the subsystem of another model. Example:
add_block('built-in/Subsystem', ['Scheduler' '/Scheduler']); -> Works(creates a subsystem named Scheduler into the top model)
add_block('built-in/Subsystem', ['Scheduler' '/Scheduler' '/Scheduler']); -> does not work (assuming I have a Subsystem named Scheduler into my top model and I want to create a subsystem within it) gives error: "Invalid destination block specification"
Thank you in advance.

Should work as long as 'Scheduler/Scheduler' exists already. In fact I just verified.
