1.Adding discount at item level in each line even if price list is selected.
2. I should be able to block a user to view my purchase price for all items. Thats ways if a user is assigned for generating invoice only, he should not be able to see my purchase price.
3. When making price list, instead of selecting individual item , i should be able to select Item Group, that ways making a price list will be much faster. (just imagine going through 500 items every-time
when you are making multiple price lists.
4. in Custom rate in price list, i should be able to select discount value instead of mentioning Rs 100, i should also be able to mention discount in %. Thats ways a custom field with Discount field will calculate 40% on my assigned selling
value automatically.

Please please add this features also.
