Saving Game With multiple slots

I am starting to follow the Epic Games Save/Load game tutorial Documentation. How would I use that to create a multiple save game slot?

For given Slots, just create a view savegames. Then if you want to save, choose in your savegame blueprint the Slot that you want (with use of umg). If you want, that the Player can type in a savegame Name and then save this to a new file, then you have a Little bit more work. You Need a TextBox in wich the Player can type in his savename. And then replace that Name with the Slot or savefile that you want to save. For loading you can search for all savegame files and print them out in a listbox.
But i think you should complete the tutorial first. And then if you are more familiar with this System, you can easily extend your savegame blueprint.
