Custom Library containing SimPowerSystems switches?

It appears that the SimPower Systems switches cannot be used in custom library blocks. I'm trying to create a custom library with a block that abstracts a three-phase inverter. When I instantiate the block in my model, I get the error:

Goto/From connections cannot cross nonvirtual subsystem boundaries.
The only exception is when a goto is connected to a state output port
Component: Simulink | Category: Model error

This error stems from a GoTo block in the IGBT Model, seen below:

Hi Abhijit, It seems that the IGBT block in question cannot be placed on its own in a model because it needs other Simscape Power Systems blocks in order to function correctly. For example, to provide the "From" for the "GoTo" causing this error, you would need to use an AC current source.

Then is it impossible to create a library of circuits? I'm trying to make a library of some circuits (for instance two-level and three-level inverters) that can be dropped into models as required.
