RMA Order level introduce pause task to hold the non-inv lines should not move to "Awaiting Billing"

RMA order has Inventory and non inventory items, current solution when inventory item is in the "Awaiting Receiving" status non inventory item is moved to "Awaiting Billing" status.

Expecting the solution to be when inventory lines are in "Awaiting Receiving" then non inventory lines should not go to "Awaiting Billing" state, we have introduced the pause task, the pause should be released automatically when inventory lines moved to "Awaiting Billing." status

Could somebody please assist me in setting the pause rule in the RMA DOO level?

Thanks in advance for the help
