enable edit for Product discount_price

Hi Guys,

I need a few words of wisdom here..

While creating a Product, before you select the product template, the field discount_price is enabled for edit..

But after we select a product template, that field is auto filled, and disabled.

What is the best to do in this case? - I need that field to remain enabled so the client can either use the calculated value, or change it to something else...
