How to setup Google Cloud Dataform git connection in a sub folder to use it in a monorepo?

Question

Is there a way to tell Dataform to store its files in a sub-folder within a git repository ?

We have a monorepo such as:

my-app/
├── server/
│   ├── package.json
│   └── ...
└── client/
    ├── package.json
    └── ...

And we would like to store our dataform scripts in the same repository to make it look like this:

my-app/
├── server/
│   ├── package.json
│   └── ...
├── client/
│   ├── package.json
│   └── ...
└── dataform/
    ├── definitions/
    ├── package.json
    ├── dataform.json
    └── ...

But the documentation only explains how to store the definitions/, package.json and dataform.json files at the root of the repository.
Is there another way to achieve this ?
