Page Jump for Sidebar Menu

Is there a way to add a page jump to the sidebar so that, when a link on the menu is clicked (top of the sidebar), you are scrolled down past the search widget (middle) to widgets further down the sidebar (bottom)?

Would be grateful for any pointers! Many thanks.

P.S. Otherwise, is there a way to add an RSS feed to a page using shortcode such that the number of items it lists can be limited? Currently using: [rss url=https://SOURCE show_date=true show_author=true show_summary=true]
