Can one use test matrix logic to define coverage combine rules?

[frere-jacques]

Is it possible to configure coverage combine with the logic of the test matrix?

I run pytest-cov over the test matrix. So far I managed to get only coverage within each environment or completely merged coverage via --cov-append.
