Is third party payment approval possible in Oracle Cloud ERP?

Content

Is there an ability in Oracle to send payment batches to third parties for approval?

Here is the use case:
Construction project A is partially-owned by Z Corp.
Construction project A is partially-owned by Y Corp.
Company B does work on Project A
Company C does work on Project A
Companies B and C bill Company D
Company D gathers the invoices in to a batch and needs to have them approved by Z and Y
Once approved by Z and Y, Company D pays Companies B and C

Challenges I see with this are:
1.    Companies Z and Y are not suppliers in Oracle, so the e-mail addresses are not there, etc.
