I doubt it. It may not be available.
You may try to add
:before attribute.. Here is a sample:
Go to http://crunchify.com/about/. Checkout true mark for heading as below:
This one was added using below CSS code:
content: "\f058"; // <===== you need to replace that with caret code.
Hope that works.
NOTE: this will add your font-awesome font for each menu item. You also need to find CSS property for it.
