Unfortunately, to our knowledge, this feature is not available with Social Articles plugin. We think that this feature requires custom development work.
Please note that this issue is related with the customization of a third party plugin, not with the use of your theme. As theme authors, the installation, setting or debugging of third party plugins isn’t part of the support we will provide.
To go further, we invite you to ask for more help from the plugin authors and post your request on their support forums. They might have a solution that we don’t know of: Social Articles support.
We remain available for all support requests related with the use of your theme.
