Macro with "file save as"

I am trying to create a macro that saves a copy of a specific SolidWorks assembly file within an open assembly. I want to give the user the ability to save the copy in a location they choose. I am able to create the macro within SolidWorks, however, it doesn’t give the user the ability to select where they want the copy to go. Can anyone help me?SolidworksApi macros
