Using reward points as a prepaid system?

Hi ppl,

nopCommerce currently do not have a prepaid system yes? It shouldn't be hard to change the existing reward system so we can use it as a prepaid system yes?  

I am assuming we just need an interface in Admin so we can "reward" customer on a manual basis and if we can take it further, a product type of "reward" that "tops up" reward points as customer purchases them. (we can even set the purchase price and the reward price (which can be 10% more or etc...))

Are my assumptions correct? or am I way over my head here?  

I would really appreciate it if someone can show me how to do the Admin interface to manually top up reward point part though.  Any help/info is greatly appreciated.  

Thank you for your time.

[EDITED]
I am sooooo sorry.... I finally found the ADMIN INTERACE to add REWARD POINTS.   :P
Please just ignore that part.  Regarding the product type of reward however.... Any help and info is greatly appreciated.  Thanks!
