Filter Duplicate View Names then append Letter to Duplicates

Does anyone have a lead on filtering out Elevation Names that are Identical so that I can rename them with the Set Parameter By Name Node?

I currently have about a dozen duplicate elevation view names based on room name and direction and would like to append an A, B, C… etc. with the string insert node to all the duplicates

Any help is much appreciated

You can’t have identical view names in Revit, so do all of the views names end in “Copy __”? Because then you can filter by “string contains”

Maybe he has culled multiple instances of the same elevation? If so try UniqueItems

yes, thank you. Looks like the unique items is exactly what im looking for. Im going to have to give that a try tomorrow… Thanks again for the response.
