General Use differents fonts

Hi,
I would like to use two differents fonts : the stock ones for icons and iOS 7 beta 1 fonts for all the others texts on iOS. I tried to do that using BytaFont 2 for beta fonts and Springtomize 3 for stock fonts, I can use two differents fonts with that however Springtomize 3 doesn't seem to have the stock iOS 7 fonts in the icons fonts list.
Is there a way I can do that ?
Thank you very much.

 

Ah it was available in previous versions...
Too bad they cut that feature hope they'll bring it back one day.
