Can I create two different keyboard shortcuts for the same command? The Preferences.app > Keyboard > Shortcuts pane allows for the creation of shortcuts to activate menu commands. However if that menu command already has a keyboard then that shortcut is overridden by the new shortcut. 

For example, the Paste menu command - I would prefer to use more than one shortcut to execute that command.


Command + V
Shift + Insert 


How do I prevent the second addition from removing the first that so that I can create as many keyboard shortcut aliases as I want for a given menu command?
Look into using the application "Keyboard Maestro" as a possible solution to your problem.
