Posting official trailer on a film title

Hi IMDb community.

I need some help. We all know IMDb is a minefield and whilst I have my head wrapped around most of it, I'm having significant trouble trying to add an official trailer to a film title page.

Now, before anyone responds and says it's easy, yes, I already know about the:

Edit Page > Links To Other Sites (Section) > Trailers/Video Clips etc.

That adds a trailer to the title page, but it adds it into the same area where your photo gallery is for the title and that is NOT what I am talking about.

I am talking about how to add the official trailer very large, to appear right beside the film poster at the top of the title page, use this film as an example: https://www.imdb.com/title/tt4303930/ (screenshot of this attached)

I know one used to be able to do it by adding it via Withoutabox, but now that Withoutabox is no longer, how do we actually do it? It's driving me crazy that someone thing so simple is incredibly difficult to find any information on.

Any assistance would be greatly appreciated. 

Thanks all!

Adam
