Is it possible to do mass change at the Component level

Hi,

I have the following Client Requirement:

The initial planned price at the component level is Rs.250/-.

There are 200 such WBS elements for which the components are attached and price is entered as Rs.250/-

Now the price has increased to Rs.300/-

Is it possible to do a Mass Change in Project Structure to the Components so that the new planned price is updated as Rs.300/-

Thanks,

S.Raghavan
