I don't think anything other than Pro has the Insert Floor option, but you can do this.

Create a new, blank Floor 3.

Drag a marquee around everything on Floor 2 and select Edit> Cut.

Go up to Floor 3 and select Edit> Paste> Hold Position.

Repeat to move Floor 1 up to now blank Floor 2, leaving an empty Floor 1 for you to draw the lower level on.
