Transfer child company stock between two facilities belonging to different parent company

Summary:

I have 2 facilities (Facility 1, Facility 2) owned by Parent company A.

Each facility has company A and company B operating in it.

Is it possible to transfer company B inventory from Facility 1 to Facility 2?

From my testing I am unable to see facilities with Parent Company = Company A available as destination facilities when creating the transfer order. I can see facilities with Parent Company = Company B only, despite both companies being configured in each facility.

Any transferred stock would remain belonging to customer B.
