Are you trying to move a group of items between two lists? You can accomplish this in several ways by using the Copy Item or Copy to Sharepoint. These will copy one item at a time, but you can get creative with some logic and workflow design to deal with more than one item at a time.
Although you cannot copy multiple items on a single action, you could use the action named "Copy to Sharepoint".
You could create a workflow on that list and start this worklfow on every item you want to copy.
