Is it possible to justify the text in "String object" ?

Hi everybody !

All is in the title ! ^^
Ok ok... i'm going to rephrase here.... so : Is it possible to justify a text using String Object ?
it's for a WebSite using html5 exporter but i want it to know for all exporter that's why i place my message in the forum "Fusion 2.5" and not in the "html5".

If no, can we have another solution to "justify" ?

Thanks for all.

Regards.
