Hi @simonasdev, thanks for the PR. This seems like a useful addition.

Before I can merge and cut a new release, would you be able to:

• fix the lint issues,
• add tests, and
• add documentation?

I can help with those but I'm not sure when I'll get to it

[simonasdev]

I've fixed lint issues and added documentation, but not yet sure how tests should be implemented. I guess I would need a fixture specific for this new option

[oliverroick]

Thanks for making these changes.

For testing, the best way to to this is to:

• Add a fixture here
• Add a couple of tests, similar to these

I can have a look at those over the weekend, if you need support

I wasn't able to push the tests to your branch. I'm merging the PR and add the tests separately
