[plugin: Pie-Register] Feature request: different Paypal prices

I wanna use the Paypal integration feature but i wanna set up different buttons each one with different prices, so a user can choose the “package” that would like, it is possible?

I guess for example i enter the different Paypal details on the settings administration page of the plugin, then on frontend registration page will show a radio button or a combo box where the user can choose it.

It will be a little different from other membership plugins, because will be not based on duration.
