Hey Randy,

in the upcoming pytest-cov 2.0 you can easily create different data files
for each tox environment and automatically combine them at the end of the

Unfortunately, there is no release date yet as I'm pretty busy right now.
However, the 2.0 branch should be quite stable, so you could give it a try.
