How to change "icons" for "numbers"

Hello… Congrats for the amazing template.

I have one question, is it possible to change “icon” for “numbers”.

Ex:

I would like to use this Service title, but with “number” not “icon=”1″” for a number l like position, is it possible?

[section]

[service title=”Apresentação” size=”col-6″ link=”#” icon=”1″ layers=”true”]Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent rutrum malesuada velit, ut vestibulum lacus tincidunt vel.[/service]

[service title=”Textos” size=”col-6″ layers=”true” last_column=”true” link=”#” icon=”3″]Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent rutrum malesuada velit, ut vestibulum lacus tincidunt vel.[/service]

Thank you so much.
