Ability to group lines on pick slip for the same item with aggravated total quantity

Summary:

Content (please ensure you mask any confidential information):

For out internal transfer orders, we currently group pick slips by Customer, Route (Carrier), and Item Category. However, when the same item appears on multiple orders for the same customer, route, and item category with different quantities, the item is printed as separate lines on the pick slip.

We would like to explore a solution to consolidate the same item into a single line and display the total aggregated quantity across all applicable orders. We did checked the group by item as an option on the pick slip grouping rules but it creates separate pick tickets for the items.
