Workflow orchestration manager dependencies between multiple Data factory accounts

Hello All,

I am looking into a use case where

1. I have a workflow orchestration manager in Data factory at subscription A

2. Another workflow orchestration manager in data factory in subscription B

Both data factories are available in the same region east US

i created a pipeline(airflow) in Subscription A but should also make pipeline created in B as a dependency. In other words pipeline A is dependant on B. 

Is this possible with workflow orchestration manager in ADF or is this use case supported.

Also if i have to accomplish the above task with data factories in different regions(one in US and other in East Asia) is this also possible?

Thank you in advance
