I am sure this is somewhere but I couldn’t find it.

@Darren_Murphy mentioned Helper Tables as en example why duplicating CC is good…I just duplicated a Helper table since I needed all the reporting already built but for a slightly different user class…

…oops…all the computed columns are gone so I have to - hopefully without error - recreate a lot of columns.
