How to get updates for a pyproject.toml/requirements.txt setup?

[pamelafox]

I have a project where I generate a requirements.txt based off a pyproject.toml file using:

pip-compile --output-file=requirements.txt pyproject.toml

The way to update that would be:

pip-compile --output-file=requirements.txt pyproject.toml -U

What's the right way to specify that in my dependabot.yaml? I've tried various permutations of pip/pip-compile with grouped/ungrouped but havent found a winning combo yet. Thanks!
