Icon Set

Hi,

Anyway to add additional icon sets so i can select them from the Enfold Icon menu. I tired using WP SVG Icon by placing the <Span statement in the text, though when i go back into the text the code has gone. So two part question, can i add more icons, and how can i edit the HTML properly as it is not selectable once the AVIA builder is used. Click on the text box and nothing in there?

Cheers
