Rename multiple files or photos at once

There should be an option like I have seen on another cloud storage company that lets you select multiple files and rename them at once. It allows you to select multiple files and if you select 7 photos and rename it "myCar" it will automatically rename them with a counter and rename them as mycar1.jpg, mycar2.jpg, mycar3.jpg and so on. You can try it out at Koofr cloud and see what I'm talking about
