To perhaps expound on GerdW's post: no, you cannot do it automatically. You *must* create custom code to do what you want.
I would suggest a custom right click menu, but you could trigger the code with a button or something. In fact, I'd recommend writing the code with inputs of "Full Table" and "Index to duplicate" and with an output of "Modified table". Get that code working, then you can implement that subVI inside of a right click menu, or in a button, or whatever.
The code itself will be very simple.
