Switch between Model and drafting - Master Model (Nx 8)

Hi,

I am using TC 8 and Nx8. Mostly of the model and drawings will be done using Master Model concept. Is there any easy way to switch between the model and the drawing. I wanted to switch between the respective model and the specification (drawing). For example, if my model name is "test" and the specification name "c_test", the switch should between these two? Is there any easy way to toggle? . May be using journal?.

Thanks in Advance
