vscode launch.json自动生成的内容怎么修改？

如题，怎么修改 vscode 中创建配置时 launch.json 中的内容？即我想创建自己的配置内容作为下次内容生成模板，而不是每次都自定义修改。

launch.json

{
            "name": "G++ Debug",
            "type": "cppdbg",
            "request": "launch",
            "preLaunchTask": "g++dbbuild",
            "program": "${fileDirname}/${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }

task.json

{
            "label": "g++dbbuild",
            "type": "shell",
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared"
            },
            "command": g++.exe",
            "args": [
                "${file}",
                "-g",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}.exe",
                "-Wall"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
