additional simscape electronics floating reference?

 Hi,
 is there a way to create a simscape component that acts like a floating reference to simplify drawings for use with simscape electronics in matlab 2016a? 
I am working on electrical DC-DC involving transformer for isolation of primary and secondary side. On primary side I can use multiple electrical reference blocks to simplify drawing, on secondary side I need to connect everything together.
Regards,
Tsing

It is possible to create custom Simscape components:

Is it possible to create a floating reference?

If your simulation does not include any coupling to the environment from the secondary side (such a capacitance to the global earth ground or chassis), then there is no need for a floating reference: you may use the primary ground as it is completely equivalent for simulation purposes only (of course, the real circuit will be galvanically isolated, but it will also have some coupling to the global earth ground).

Similar to SPICE tools, Simscape solves voltages in an absolute sense so a notion of "zero" is always required since it is only voltage differences that have meaning in electronics.
