Rolling multiple items into single invoice item?

Is there a way to get multiple invoice items to be listed as a single summary item? For example, I sell a packaged item (custom gizmo 1) that consists of (part 1, part 2, integration labor).

Ideally, I would like to track each part and integration labor separately for budgeting, but have this presented as a single item line item as the customer.

You can setup “custom gizmo 1” as inventory kit under Settings tab. Inventory kit is a special inventory item which consists of multiple inventory items.
