To group a series of zoom/pan operations into a single step for the UNDO command you need to set the bit 16 of the UNDOCTL variable.

If this variable is set to the value of at least 17 (default value is 21), the Undo function undoes zoom operations in one step (AutoCAD 2006 and higher).

See also Options/User preferences - Undo/Redo.
