Header + Text (social networks) in General Setup (Shopperpress)

Hello – I have both Shopperpress and Realtorpress and in SP Header + Text (social networks) in General Setup you can input your social networks and in the header there will be icon and link to your affilated social networks i.e. facebook etc.

This functionality is not in RP – any suggestion on how I can add (Linkedin) to my header in RP?
