One dirty trick might be to do a ReplacePart on the original list to differentiate the element first then use this trick but that doesn't seem like a professional way of doing it. Is there a function that can target positions directly?

...or cyclePart[list_ -> drop_, n_, \[CapitalDelta]n_, cycle_: True] := Module[{newlist = DeleteCases[list, Alternatives @@ drop]}, cyclePart[newlist -> {}, PositionIndex[newlist][list[[n]]], \[CapitalDelta]n, cycle]]?
