Current behavior: I'm trying to migrate a large application from Browserify to Webpack/karma-webpack. Karma-browserify has an option to pass additional options during bundle events, as detailed here. From what I can tell, karma-browserify lacks this ability. It would be great if this does in fact exist.

Expected/desired behavior: Ability to do something like the following (inside karma.conf.js):

        browserify: {
            debug: true,
            transform: [
                'stringify',
                brfs
                /*, 'browserify-shim'*/
                , istanbul({ ignore: ['**/assets/**', '**/dist/**', '**/test/**'] })
            ],
            configure: function (bundle) {
                bundle.on('prebundle', function () {
                    bundle.require('./test/mock/session-new/', { expose: 'session' });
                    bundle.require('./test/mock/session-new/s2', { expose: 'session.s2' });
                });
            }
        }

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem along with a gist/jsbin of your webpack configuration. This doesn't appear to be a bug; it appears to be a missing or undocumented feature.

• What is the expected behavior? I'd guess something analogous is possible using a combination of additional config options: https://github.com/webpack-contrib/karma-webpack#options but I don't know how to make this work.

• What is the motivation / use case for changing the behavior? Enable feature parity with karma-browserify

Currently you can pass the entire webpack configuration. Is there something specific that you're unable to do currently? Let me know if this is something you're sill interested in.
