Custom Icon in Tab Title

Hello. We’ve been looking to purchase the Max Megamenu plugin but what we want to create with it requires inserting custom icons inside the Tabs title. I know you can make menu items with a custom icon but I’m not sure if they’re supported in the tabs section and I haven’t found anything that shows that on their website.
Does anyone know if this feature exists? Thank you in advance.

Here’s an example of what we’re trying to create: http://f.cl.ly/items/0Y393s1B2J1p1x3b3a3T/Image%202019-02-25%20at%207.21.47%20pm.png
