How can we do a bulk update of Expense Report Status via SOAP UI

Summary:

We need to change the status of some 1000+ Expense Report numbers to "MGR_REJECTED". We know how to do this via SOAP UI one by one. But since there are so many reports that need to be updated, we would like to explore the possibility of doing this update in bulk.

Is there anyone who has done a bulk update for the Expense Report Status via SOAP UI and can help us?
