Is it possible that you could add an option to have 'quote-source' be something like mysite.com/node/1#comment-1? Instead of going to a separate page, it would link to an anchor on that same page.
Perhaps integrating tokens might work.
I'd love to help, but I'm not a coder.

I am closing this issue, which was created for a project version compatible with a Drupal release no longer supported. Feel free to re-open the issue, if it is still relevant for a project version compatible with a supported Drupal release.
