Complex generated matrix

[Alex Graber]

I have a tox testing plan that generates a complex matrix of environments to build against. Is it possible to run these with tox-azure?

Here's a trimmed down version of my tox.ini

envlist =
    py{37,38}-np{18}-pd{0,2}-sci{14,16},  # test conflict btwn numpy, scipy, and c extensions
    py{37,38}-np{19,20}-pd{0,2}-sci{15,16},
    py39,  # latest version of python, assumes 'latest' for dependencies
ignore_basepython_conflict = true
# isolated_build = true

[testenv]
basepython =
    py37: {env:TOXPYTHON:python3.7}
    py38: {env:TOXPYTHON:python3.8}
    py39: {env:TOXPYTHON:python3.9}
deps =
    pytest
    pytest-cov
