Rewards Points Suggestion

Hello,

I would love to see an option for products to:

1. Disable a product from getting rewards points.
2. Disable a product from being purchased with rewards points.
3. Make a product "Rewards Points" only instead of cash.

It's a great system as is, but it feels quite limited with it's potential.

Thanks a lot for suggestions. I've just created three work items:
