Change Coordinate System Dynamically

Question

I created a Layout Frame with the area of interest zoom to fit the layout and has a GRID Coordinate System of GDA94 MGA Zone 55.

Note: This a series map which MGA Zone keep changing depending on the area of interest.

On the Content Pane, below are both in GDA 1994 MGA Zone 56 coordinate system.

Map Properties GDA 1994 MGA Zone 56

Format Map Grid GDA 1994 MGA Zone 56

How do I dynamically change the Format Map Grid and Map Properties to match the area of interest Coordinate System shown below which is in GDA 1994 MGA Zone 55. In this way the grid line will align to True North.

The area of interest from the Layout Template which is Zone 55

Do I understand correctly that you have a map series where the different pages should have different CRS? Would your problem be solved by adding a field "CRS" to the feature class defining your map series, in which you put the coordinate system for each page, and then when setting up the Map Series under "Optional Fields" set the "Spatial Reference" to this field?
