Find a way to filter concept exercises by taskno from the command line (concept exercises)

Hi,
Pytest test suites in Exercism contain custom marks in the form of `@pytest.mark.task(taskno=X)` where X is a whole number. At least in concept exercises, this number corresponds to the task inside the supplied README file.
While doing a concept exercise, I wanted to select pytest tests to run and filter them by this `taskno` parameter but failed to do so. What I tried:
1) @BethanyG sent me a [link to StackOverflow thread which shows one similar problem](https://stackoverflow.com/questions/67200501/pytest-run-only-tests-with-specific-marker-attribute):

However, the example code allows to run marks with arguments looking like this:
`@pytest.mark.task("taskno1")`

Perhaps there is a way to modify something in the conftest functions but I haven't wrapped my head around it.

2) I tried a plugin called [pytest-pilot](https://smarie.github.io/python-pytest-pilot/)

It supplies easier syntax for solving similar problems as `1` but also didn't help me solve the problem. I would get an error `IndexError: tuple index out of range`.

What I use now:
1) `pytest -k keyword_you_need`
It usually works, but sometimes I still select more of fewer tests than needed
2) `pytest --tb=short`
I don't like long error messages from pytests so this is another way to limit pytest from adding too much unwanted output.

Filtering by task number would be "nice to have", but I think solving this problem is interesting in itself. All help is welcome :)
