Set font-family of text from in SmartForms

I do a Include Text from my SAP SmartForms, which created from Text Editor (/nSO10). How can I set a font type to the text from the text editor? I do not want to use ABAP to do anything with the text. But it seems that in SmartForms,I have no way to change the font-family of the text from the text editor (/nSO10).

Please help. Thanks
