Smart Search Button with Font Awesome icon

Hi,

Im very new to kentico development wise and I'm trying to work to a design given to me.

I'm currently trying to tie up the smart search web part to show as a text input with a font awesome search icon as the button (with no button text). Is there any easy way to do this? Or should I resort to making a copy of the Smart search control and extending it out?

The html designed has just

<button type="submit"><i class="fa fa-search"></i></button>

is there an easy way to put this into a new layout for Smart search?

Thank you Andrew
