Yea there's a way Select a sample text. then add to "Character Styles" then right click the character style and select "Highlight on Canvas". Then right click again and click edit. You can now mass change the font. When your happy you can delete the character style.
In a bigger way, you can select all the canvases then add to "Character Styles" Then mass edit all the fonts that way as well
