is it possible to format a centre spread across 2 facing pages

I'm trying to create a newsletter, printed on A3 paper and folded in half so it's a 4 page document, each individual page being A4 size. I want the centre pages, ie pages 2 and 3, to be combined into a centre spread - so images, text boxes etc can span across the 2 pages. I'm using page layout setup, ie "Document Body" is not selected, and "Facing Pages" is selected.

This is something I've been doing in ms publisher for some time, it's called "booklet, side-fold". Pages doesn't appear to have booklet style templates, and I can't find any help about this except a couple of questions from like 10 years ago.

Is it possible? I have found publisher to be quite frustrating and I wanted to switch to pages, but if it can't do the centre spread I guess I'll just have to stick with publisher.
