Can you change the order for rendering group?

"rendering": [
            "render",
            "/^render.+$/"
          ]

[edizcelik]

    "react/sort-comp": [
      2,
      {
        order: [
          "static-methods",
          "instance-variables",
          "getters",
          "setters",
          "lifecycle",
          "everything-else",
          "rendering"
        ],
        groups: {
          rendering: ["render", "/^render.+$/"]
        }
      }
    ],

@bedirhankaradogan This should be the latest configuration for this rule.
