Status Mapping in Document Type BP

In a Document Type Business Process, we have 2 Statues:

1. Workflow Status: Approved, Under Review and Rejected

2. Line Item Status: Approved, Under Review and Rejected

If line item status is equal to approved then only document will be published in document manager.

Now my question is, Is there any way to map these statues?

That means, we if select "Approved" as Workflow status then Line Item Status will be changed automatically

Because user is doing this type of mistakes. He approves the record but forgets to change the line item status. Due to this document goes to Unpublished documents.

Please help me to get out of this.
