Run custom command before builtin pipeline

Question

How can I run a custom command before running a provided pipeline?

Specifically I want to:

poetry export -f requirements.txt --output requirements.txt

then run the google-app-engine-deploy pipeline.

I understand the 'steps' are in different docker containers, so I can't run this in the previous step, correct?

After seeing this used in ssh-run for envsubst, I found out you can simply:

- step:
script:
    - pip install poetry
    - poetry export --without-hashes -f requirements.txt --output requirements.txt
    - pipe: atlassian/google-app-engine-deploy:0.2.1

Most examples with pipes have only a single 'line', and the step/script terminology was a bit confusing, but this works fine.
