Hi ciaranhyde,
It needs lots of code customization. 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.

If you like to make a changes on the code then go to theme directory -> library -> structure -> header-extension.php on line no 271 and add below code
if( is_home() || is_front_page() ) {
// add your shortcodes here
}
Thank you!
