Is there a plugin to easily edit the VS Code theme?

Question

Visual Studio Code

For example, I need to change the highlighting of some control statements (if-else, etc.). Now I have to fix it in Settings.json:

"editor.tokenColorCustomizations": {
        "[Default Dark+]": {
            "textMateRules": [
                {
                    "scope": "variable.scss",
                    "settings": {
                        "foreground": "#4be772",
                        "fontStyle": "bold"
                    }
                },
                {
                    "scope": "keyword.control",
                    "settings": {
                        "foreground": "#b80d85",
                        "fontStyle": "bold"
                    }
                },
            ],
        },
    },

Is there a plugin that simplifies this setup?
