@TPDBS How about using a slice?
How about using a slice
Insert a pair of value and position.
However, for the position at index 0 (first), this method will not work. Try it.




SET List TO [1, 2, 3, 4, 5, 6, 7, 8, 9]
SET Insert TO [999, 2]
SET Insertvalue TO Insert[0]
SET InsertPosition TO Insert[1]
SET sublist TO List[:InsertPosition] + Insertvalue
Variables.MergeLists FirstList: sublist SecondList: List[InsertPosition:] OutputList=> List
