Customize filename in webpack

Question

I am using webpack extensively and my config looks something like this —

{
    entry: {
        main: './d11-web/lib/bootstrap.ts',
        sw: './d11-web/sw/sw-bootstrap.ts',
        kill: './d11-web/sw/sw-kill-switch.ts'
      },
      output: {
        path: path.resolve(__dirname, 'public'),
        filename: '[name]-[chunkhash].js'
      },
}

The problem is that I want sw and kill files to not have the [chunkhash] appended to their name, where as for main I do want the [chunkhash].

Is there a direct way to achieve this or via some plugin? If its a plugin what property should be updated on what event so that the file names are as per me.
