Yes, You need two copy.

Or, you can use image_list plugin.  https://www.ventoy.net/en/plugin_imagelist.html

Code:

{
    "image_list_legacy": [
        "/ISO/Legacy1.iso",
        "/ISO/Legacy2.iso",
        "/ISO/Legacy_UEFI.iso"
    ],
   
    "image_list_uefi": [
        "/ISO/Uefi1.iso",
        "/ISO/Uefi2.iso",
        "/ISO/Legacy_UEFI.iso"
    ]
}
