Customer wants to have charge account in the cart and updatable

Summary:

As in the classic UI ie self service purchasing we can update the charge account of the copied line in the same screen as line and billing details are on the same UI, But in the redwood its not the same process, if the user copies a line and want to charge it to different account you have to go edit and delivery and billing tab and edit to charge account, this takes time if there are more than 20 lines to be copied from different items and charge it to different account

we were able achieve the charge account in the cart UI of the redwood but we cant update it,
