How to scroll down only a section of webpage

I am trying to scrape all of the current ticket prices on Ticketmaster for an upcoming NBA game. The page automatically loads more tickets when you scroll down, but only when you scroll down in the tickets section of the page, not when you scroll down the whole webpage. When I run the scraper currently I only collect the first 40 tickets or so that are loaded with the webpage, but I want to be able to collect all available tickets.
