If you mean, how to do the 'zoomed' sub-assembly exploded view, I've never tried, but off the cuff as a first crack, I would make the exploded diagram for the assembly moving the sub-assembly like shown, then add the "Smart explode lines" for that sub-assembly. When you add it to the drawing, you could use a crop view to remove the sub-assembly from view, but keep the smart explode lines. Then make an exploded diagram of the sub-assembly and add that drawing view to the assembly drawing (you could do this in the sub-assembly file or in the assembly with other components suppressed in a new configuration). Finally, once you then move the sub-assembly drawing view into place, you 'attach' it to the assembly view so it would move in tandem.
If I get a chance later today, I might give this a try. Could be useful to have something like this for complex assemblies (when there's enough space on the sheet of course).
If I misunderstood your question, please provide additional clarification as to what you're looking to accomplish.
