I often create additional views in assembly drawings and place appropriately for (in my case) 3rd angle projection.
In such cases, I delete the section arrows and derived view title since they are not necessary and just add clutter to the drawing.
If the detail is updated, the section arrows come back (although the view title remains gone).
I understand you may decide you want the section arrows back in some cases so I propose this solution:
In the detail properties dialog for the derived detail, simply have a checkbox for section arrows and title to be on or off.
Clearly if off, the function "_AstM9CommDetRenumberCuts" must ignore any that are off when re-labelling other cut views.
