[Theme Horse Support Team]

Hi ade.newton,
We are sorry that we don’t have this feature in our free version of theme. You may customise code but We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.

Thank you!
