Hello Guys, I observed that salesforce billing package does not have button to cancel all invoices at one go. Earlier before 7.0 version they had a button on invoice run to cancel all invoices which is discontinued now. They have 'cancel and rebill' option over individual invoices. My use case is to cancel all invoices at one go, any recommendation or any Api exposed by salesforce billing to do the same?

I found a method within the package which accepts single invoice Id to cancel at a time but i am afraid how will it work for bulk invoices. Please suggest
