Testing on multiple versions of chrome at the same time

In our product we support the most recent versions of Chrome + a fixed version in the past that we bundle in our native apps. This doesn't seem possible with the env variables, is it possible to pass a binary location to a customLaunchers config object?

I think I've found a solution which is to start Karma multiple times with a different CHROME_BIN environment variable. This isn't ideal though, I'd like them all to run concurrently through one Karma test run.
