Custom commands for Pytest build step Follow

I'm using Python implementation of Playwright framework.

To install it I have to

• create virtual environment (venv)
• install all requirements from requirements.txt
• run command `python -m playwright install chromium`

I tried to use the default Python runner type in 2 steps:

1. Command=module; module=playwright; Script or module arguments=install chromium; Environment tool=venv
2. Command=pytest; Environment tool=venv

This approach forces the build to run venv creation/activation and pip install -r requirements.txt two times which I want to avoid.
Is there any workaround to run `python -m playwright install chromium` after requirements install and before pytest launch?

I know that I can create several custom scripted steps to reproduce the behaviour of standard Python runner with pytest command but I want to configure standard one.
