Where can I set defaults for all that fields you have to enter when you add a product?

Most of my product require the same settings
Product is Free: No
Product is Call for Price: No
Product Priced by Attributes: Yes
Tax Class: --none--
Products Price (Net): 1:40
Products Price (Gross):
Product is Virtual: Yes, (downloadable goods)
Free Shipping No, Normal Shipping Rules
Quantity Box Shows: No, Do not show Quantity Box

That will keep me from making mistakes by forgetting one or two:S

Thanks

Bert
