Is it possible to disable Stop Words functionality?

I want to migrate to this plugin by Yoast on my popular site http://www.learnqtp.com/

The only thing that is stopping me is that it automatically removes stop words from the slug. Now since this is an old blog, it has lots of those and I don’t wish to do manual redirects for the posts published earlier.

There should be an option perhaps to disable this functionality.

I can see multiple people have posted in this regard earlier http://wordpress.org/support/topic/plugin-wordpress-seo-by-yoast-disable-post-slug-stop-word-modification?replies=5

Is it possible somehow?
