Moving author title and date to one column of a two-column page with markdown and pandoc for a PDF output

Question

I am trying to produce a landscape-orientated page that is two-column. I want the author, title, and date to appear in the left-side column. I set up the two columns following the answer here.

Currently, the author, title, and date are centered at the top of the page, and the rest of the page content follows below as two columns.

Here is the YAML header I am using:

---

title: Test
author: Name
date: \today
papersize: letter
fontsize: 11pt
documentclass: article
classoption: 
  - landscape
geometry: "left=2cm, right=2cm, top=2cm, bottom=2cm"
Header-includes:
    - \setlength\parindent{0pt}
    - \usepackage{multicol}
    - \newcommand{\hideFromPandoc}[1]{#1}
    - \hideFromPandoc{
        \let\Begin\begin
        \let\End\end
      }

---

is there anyway to shift things so that the intro material appears in (or maybe just above) the left-side, such that the right-side column can use the entire page length?
