Display Lot/Serial Numbers in a separate list without repeating item lines in the delivery note

Hello everybody,

I have the following scenario:

A set consists of two components:

• a certificate,

• a 20-item box, which can contain one or more lot/serial numbers.

In the delivery note, the information should be displayed as follows:

1. Line for the certificate

2. Line for the item (20-item box)

3. Below the item line, a list of all associated lot/serial numbers should appear – regardless of whether there is one or multiple lots.

The lot/serial numbers come from the field:
[SOShipLineSplit.LotSerialNbr]

Problem:
When I use a separate detail section for the lot/serial numbers in the report, Acumatica repeats the item line for each lot/serial number. This causes duplicate or multiple item lines, which is not desired.
I need a way to display the item line only once and list all associated lot/serial numbers below it in a single consolidated view.

Question:
What is the recommended approach or report setting to display the item line only once and show a consolidated list of all lot/serial numbers from the SOShipLineSplits underneath?

Thank you for your support!
