Change site title font to external font style possible?

Hey everyone, just started my homepage a few days ago and I am still a newbie at all this, so bare with me. I know how to change the site title font to any of the preinstalled font types that are already available in Simple Catch Pro. Most of them are ok but I would prefer a different font type from google or the internet. But how can I upload more font type options to Simple Catch Pro so that I can choose a different Site Title font? I installed the plugin "Easy Google Fonts" and it worked for everything BUT the Site Title Font itself (which is the only thing I really want to change). Thanks for your support
