Sync Users from Rich Project to Connected Project


Is there a way to sync users from a Rich Project in ProjectWise Explorer (i.e. PW Admin Userlist members) to the corresponding Connected Project members list? Currently we have Deliverables Management enabled and right-click on the Deliverables Management folder/node in ProjectWise Explorer and go to settings. If there have been any new users added to the userlists, they will show up in this window and selecting Apply or OK will sync them to the Connected Project. We would like to automate this activity in a PowerShell script if possible?
