RSSP - BPA Requisition -Need to edit line(s) quantities without the selected ones from being removed

Summary:

Searched BPA number and lines come up in the table view which is established as our default.

Checked multiple lines to be moved to cart but when I adjusted the default quantity of 1 to another number it removed the others that were checked.

How can I edit multiple line quantities without the checkbox becoming unchecked?
It is not efficient to have to reselect the line items especially if you are creating a requisition against the agreement with large amount of line items and multiple quantities.
