I hope his is possible...

I'm trying to switch from CKEditor to TinyMCE for my site, but I use inline css to apply classes to certain bits of text and can't figure out how to do this without manually writing it into the html. 

With CKEditor, I have a list of styles that I can simply apply via a dropdown menu. Does anyone know how to do this with TinyMCE? I searched for a plug-in that might add that, but don't see one.  Seems like it would be a fairly basic use case.
