How to put Score Title in score page

I am making score by Score editor.

How can I make put song title in score page?

I remember that version less than 7 ,there is some box to put the song title shown on the top of the score.
However, I can’t find that in cubase8 score editor.

There are text,Lyrics,Block Text,Lay Text,Page Text, howver
I can’t find the way to put song title.

It is indeed the Page Text. (you can right-click on the symbol, to determine if this will be inserted on the Layout layer, or on the Project Layer). When you place it in the Score, it opens a dialog, where you can set up everything you are used to setting up for Song Title.
