如何配置VSCode任务按顺序启动指定目录的Git Bash终端？

我在VSCode中开发项目时，需要打开三个Git Bash终端，分别处于项目根目录（用于Git CLI操作）、Client目录和Server目录。每次打开工作区手动配置这三个终端过于繁琐，因此通过VSCode Tasks实现了工作区打开时自动启动它们，配置代码如下：

"tasks": {
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Startup Terminals",
      // "dependsOrder": "sequence",
      "dependsOn": ["Git", "Client", "Server"],
      // Mark as the default build task so cmd/ctrl+shift+b will create them
      "group": {
        "kind": "build",
        "isDefault": true
      },
      // Start the task on folder open
      "runOptions": {
        "runOn": "folderOpen" 
      }
    },
    {
      "label": "Git",
      "type": "process",
      "command": "C:\\Program Files\\Git\\bin\\bash.exe",
      "args": [],
      "problemMatcher": [],
      // Mark as a background task to avoid the spinner animation on the terminal tab
      "isBackground": true,
      "presentation": {
        "echo": false,
        "focus": true,
        "group": "first",
        "panel": "dedicated"
      }
    },
    {
      "label": "Client",
      "type": "process",
      "command": "C:\\Program Files\\Git\\bin\\bash.exe",
      "args": [],
      "options": {
        "cwd": "./Client",
      },
      "problemMatcher": [],
      "isBackground": true,
      "presentation": {
        "echo": false,
        "focus": false,
        "group": "second",
        "panel": "dedicated"
      }
    },
    {
      "label": "Server",
      "type": "process",
      "command": "C:\\Program Files\\Git\\bin\\bash.exe",
      "args": [],
      "options": {
        "cwd": "./Server",
      },
      "problemMatcher": [],
      "isBackground": true,
      "presentation": {
        "echo": false,
        "focus": false,
        "group": "second",
        "panel": "dedicated"
      }
    },
  ]
}

该配置可正常运行，但存在终端顺序随机、位置不固定的问题。我尝试启用任务中的"dependsOrder": "sequence"选项来解决，却发现仅Git终端会启动，其余终端无法创建。推测原因是Git任务作为后台任务从未“完成”，导致后续任务无法触发。

我了解VSCode Tasks的设计初衷是运行并完成单个任务，而非用于打开终端，但这是我能实现需求的最优方式。根据官方文档：

如果指定"dependsOrder": "sequence"，则任务依赖项将按dependsOn中的列出顺序执行。在使用"dependsOrder": "sequence"时，dependsOn中的任何后台/监视任务必须有一个问题匹配器来跟踪它们何时“完成”。以下任务将按顺序运行task Two、task Three，然后是task One。

我的问题是不知道如何配置问题匹配器（problem matcher）来标记每个任务为“完成”状态。
