Link Facebook Page to Comments Plus

I’ve set up Comments+ to enable commenting via Facebook. When I comment, by default it uses my personal Facebook account and timeline, I need to be able to comment using my public figures page, how do I go about doing this?

I’ve searched the KB for this, but I was only able to find someone asking about it and it not being available back in 2013. Three years later, I’m hoping there’s a way to do this, else the plugin won’t suit my needs.

Thanks so much!
