Kits in Baan

Trying to see how best to build a Kit in Baan.

Currently, I have 2 lines on an order, a Finished Good Item and then another item to capture some cost such as freight or handling and such.

I would like to have a Kit that contains both so that I can have a single item but it contains both.

Something like:

Kit Item 123
Finished Good Item 1
Service Part 1

Any slick way to do this in Baan IVc4?

Thanks
