Answer 1

You can add it without another file open

Answer 2

Here

Step-by-step explanation:

You can add one or more slides to your presentation from another, without having to open the other file.

(By default, a copied slide inherits the design of the slide you're inserting it after in the destination presentation. However, you can choose to keep the formatting of the slide you're copying instead.)

When you import a slide from one presentation to another, it is simply a copy of the original. Changes you make to the copy do not affect the original slide in the other presentation.
