  You can use the Invoke Method activity to remove a feature at a specified index, and the Add To Collection activity to add one. Alternatively, use the Remove From Collection activity, but you need a reference to the object to remove, not its index.

   

  Example:

   

  <Activity mc:Ignorable="sap sads" x:Class="{x:Null}" sap:VirtualizedContainerService.HintSize="280,398" mva:VisualBasic.Settings="Assembly references and imported namespaces serialized as XML namespaces"
