In Pages,Insert text on top of every page, center it, and make it bold

In the Pages App, I’m trying to insert or make “Title Text” appear on the top of every page, I would also like to set the alignment to center, and to make it bold.

The body text property does not appear to have properties I can set.

I’ve made some progress with this. Apparent the “text item” belongs to a page, so I have to first tell a specific page:


tell application "Pages"
	tell document 1
		tell page 1
			make new text item
		end tell	
	end tell
end tell

I think after I’ve added a text item, I can figure out the position, alignment and font, by inspecting the properties.
