Default values for Product details

[turvas]

hi,

what is right place (file, location) to assign default values (considering some, like SKU might be computed, not fixed) if New product is created?
one candidate seems to be administrator/components/com_virtuemart/views/product/tmpl/product_edit_information.php and other files in this folder, not sure this best place to assign values , like $this->product->product_sku .

any thoughts?
