Overwrite the route similar way with NextJS middleware rewrite()

[lpph64-official]

Hi folks,

I am using the Tanstack Router (File-Based Routing) to build the multi-tenant SaaS.

routes/
├── index.tsx # Root domain index (https://root.io)
├── sign-in.tsx. # Root domain sign-in (https://root.io/sign-in)
└── tenant
└─── index.tsx # Subdomain index (https://tenant-name.root.io)
└─── sign-in.tsx # Subdomain sign-in (https://tenant-name.root.io/sign-in)

Expectation:

• ✅ https://root.io -> /routes/index.tsx
• ✅ https://root.io/sign-in -> /routes/sign-in.tsx

From subdomain:

• ✅ https://tenant-name.root.io -> /routes/tenant/index.tsx

• ✅ https://tenant-name.root.io/sign-in -> /routes/tenant/sign-in.tsx

• ❌ https://tenant-name.root.io/tenant -> /routes/tenant/index.tsx

• ❌ https://tenant-name.root.io/tenant/sign-in -> /routes/tenant/sign-in.tsx

It's kind of similar with Next.js middleware rewrite

module.exports = {
  async rewrites() {
    return [
      {
        source: '/tenant',
        destination: '/',
      },
    ]
  },
}

I have tried to use the Code-based Route. It works, but I would like to use the File-based instead, how can I do that?

same as #3188
