linked orders

[beetea2]

We got 2 orders recently from the same customer, one right after the other, but just one payment (which covered the cost of both orders), and ThirtyBees marked the orders as "linked"

I tried to reproduce this feature on my test site, but don't see any way to link two orders.

It's a really nice feature, but how does it work and how can I link two orders?

TB 1.5.1 with PayPal payment module.

clarification

[Yabber]

Such a split order is created if each product in the order has a different carrier assigned to it.

Or if some products use ASM and some not.

Thanks for both your replies. ASM is Advanced Stock Management? I'm not using it (as far as I know), and none of our products have any particular carrier assigned, but you've given me some clues to investigate further.
