How to Write features in a specific order / Hierarchy?

Hi Community,

I'm working on a workflow that needs to write a final Feature class based on a particular hierarchy. The workflow includes a few 'AreaOnAreaOverlayer' steps + ListConcatenator to indicate which parcel overlaps which, below a screenshot with the desired hierarchy:

1 - Most important parcels A

2- Middle important parcels B

3- Less important parcels C

I can't run dissolve + clip as need to keep the overlapping information to be 'listconcatenated' so decided to use a Sorter (alphabetical order) to obtain the desired order but isn't working 😞 as there's areas where the parcels C are on top of the parcels B.

Below an example where the overlap in the middle between 2 parcels (B + C) should be assigned to B but for some reason is C

There must be a way to tell FME please write parcel A on top of parcels B and then parcels B on top of parcels C and parcels A on top parcels C.

A>B>C

Thanks a lot in advanced 🙂
