The developers can create a custom addon for you. However, it'll start to work only for the commenters made after the addon installation. In other words, for old comments, it won't work. 

We have plugin customization and custom addon development services at the gVectors Team. They can assess the work and create it for you if you want.

Once you decide, you can contact us via salesgvectors.com email address and send a list of requirements you'd like to have.
