Hi,
I am afraid that this feature is not currently available with theme . Unfortunately that is not part of the current theme functionality, and it’s not within the scope of our support to be able to provide that functionality as it is more work than a small customization. While we’d love to be able to support every customization request, we simply don’t have the time. We recommend that you seek a freelance developer if you need that functionality, potentially from one of the below resources:
