Why can not collective intercompany billing from delivery?

Hi experts,

We are using intercompany business like this:

PO ->>Replen.Cross-Company -> intercompany billing (type ZIV).

Now we can do collective biling from delivery to ZIV.

But also want to collective billing from delivery to Pro Forma Intercomp(type ZF8).

Is it possible ? How to configure this?

Thank you in advance.
