Question

1C-Bitrix

Who can do or come across, I can’t understand how to group delivery services by parent in the sale.order.ajax component?

those. For example, there are deliveries:
1. DPD
2. CDEK: door - door
3. SDEK: warehouse - door
4. SDEK: door - warehouse
5. Pickup

How can I combine CDEK?
Who faced? Or maybe I saw where someone did what, I will be grateful.
