Some Commerce field settings should be at product level

Required, especially. Let's say you create a field and you add it to 4 products. It's only required in 2. Now you have to create a totally new EXACT field, because required is set at the field, not product level.

These settings at the bottom could all be at, or overwritten at, the product level.

Display when purchasing?
Can be edited in the client area?
Required?

Thanks
