Multiple font layouts in single book


Is it possible to use multiple font layouts in single book?
I am going to use both layouts i.e. Right to left and Left to right in same book. I have tried a lot, but couldn’t get success.
If anyone know the process, please guide me.
Is there any way to create any new style for this purpose?

Can you give us a sample of the imported text with both RTL and LTR or are they in separate sections?
