Parcial payment possible?

Hi
I’ve acquired the “Advanced Booking Calendar Pro Version” recently.
All is going well, quick installation and booking registration going well (still only in the back-end, since the site is being prepared by me).

But I was trying to find the possibility of accepting partial payment from guests (50%, for example), to confirm reservation. Then, lets say 30 days before arrival, guests are asked to pay the remaining 50% do conclude booking. If booking is made in less than 30 days in advance in respect to arrival, 100% payment.

Is this possible, somewhere, in the plug in? Or do I need to manage this manually?
Thanks
