Duplicate Elements from the Palette with Code

Does anyone know how one would duplicate an onscreen element with blocks. For example, I have a map app, and I want to be able to duplicate as many markers as I need without dragging in dozens of markers and using the enable/disable function dozens of times. Is there a simpler way to do this?

Use run time Markers instead of design time Markers might be what you need to do.

National Park Tutorial (Markers) updated is an example of one possible way

Thank you so much!
