Displaying relevant fields

I would like to create a section in the CMS for products.

Each product belongs to a certain product group, for example Televisions or Cameras.

What I would like to happen is that when (via the CMS), a new product is added, once the applicable product group is selected, then certain fields relating to that product group are presented.

As an example, if the selected product group is Televisions then I would like the fields to be screen size and number of HDMI inputs whereas if the selected product group was Cameras then the fields might be resolution or other fields relating to this product group.

I don't think this is possible at the moment but can you tell me if it's on the development plan?

Thanks, Paul.
