Can one credit note be issued for multiple sale invoices under gst?

Suppose, "A" sold goods to "B" through 3 invoices in August'18. Out of those 3 invoices, few items from each invoice have been returned to "A". Now, "A' has issued 1 Credit Note in September'18 for all these returned goods.

Whether it's possible to issue single credit note against multiple invoices?

If yes, then how to show the same in GSTR-1 for the quarter Sept-Dec'18?  In the GSTR-1, I couldn't find any option to include multiple invoices against single credit note. What to do?
