Grouping response files per unit test?

[alex-harvey-z3q]

Placebo is a great tool but I am finding the behaviour of Placebo to read from response files that are internally numbered from 1..n makes it difficult to structure maintainable unit tests.

Would it be possible to add a feature, maybe some kind of counter reset mechanism perhaps? that would allow us group response files in separate directories on a per test case basis to make it easier to make understandable code? Or is this already possible somehow?
