Split Bundled Product in delivery note

We are service provider to supply & install electronic product, we mainly selling on e-commerce platform.

Our workflow is customer purchase Doorlock with installation on ecommerce platform. Warehouse ship the doorlock to customer, after that local partner go to provide installation service.

We created a items:

  1. Doorlock
  2. Installation Service
  3. Doorlock with installtion service( Bundle Product ) - same SKU with the ecommerce platform

Expected behavior:
When warehouse ship out the doorlock, we expect to create a delivery note contain Doorlock only, and after the local partner provided installation service then we create delivery note of installation service.

then Sales Order is complete delivery.

In actual:
When warehouse ship out the doorlock , we unable create delivery note that only contain doorlock for the sales order which contain item Doorlock with installtion service( Bundle Product ).

We don’t like to split into two item in sales order.
