Create Custom Menu to wrap Selected Cells in IFERROR formula

Hi,

I want to create a custom menu option when I highlight cells and right click. The menu opton will say "Wrap Selected Cells in IFERROR"

When I select this option, the macro will basically wrap all cells that are highlighted with IFERROR and the IFERROR value returned should be a blank ("")

Can anyone help me do this in a simple way? I want this always available so I guess it should go as a module in PERSONAL.xlsb?

Thanks!
