I am not sure if I understand the problem correct.
Activating a fault tree will initialize its content based on a failure net. You could e.g. create a variant and exclude failures from the variant which should not be taken into account when you create a fault tree. Afterwards you can delete the variant.
If you are in a fault tree it is not only possible to show minimal cut set but alternatively use „File – Export – Export minimal cut sets (*xlsx, *xls)…“
The resulting document has a column with the order.
