Price List Item Modify/Update Process?

Hi All,

I have Requirement.

Normally in Sale Orders we are using "Price Lists".

Price List are maintained by specific users.

Issue:

For example if user wants to modify the price of 100 products in particular price list then there is no automated process is available in siebel.

currently users are doing this process manually in my organization.

I wants to know that is there any way from where we can modify/update prices in price lists.

I know that we can use import objects for new price lists and price list items but it will not useful in case of modify/update product prices.
