new controls: upload and nested radio list

Hi,

Thanks for creating such a nice product, however i want to do some custom development into it.

1.  I want to add upload control for the product variants, i want some files from my customers.

2. I want to show some controls when the customer selects a option, in other words i want to show a text box when customer selects a radio button.

Is it possible?

AFAIK, all the things you wish to add to the system are doable with asp.net knowledge and some learning of how nopcommerce works.
