Bootstrap stack columns and change order

Here's an image of what I would like to change

Currently the page has 2 main columns, a sidebar on the left with some rows and a main body on the right. A 3x9 setup. I want the 1st row on the 1st column to move to the very bottom in a mobile view. I thought about seperating the 1st col into 2 different ones and stack them on top of each other and then just change col order on mobile view. But I have no idea how to achieve that...

How the grid looks in html:

<div class="container">
  <div class="row">
    <div class="col-lg-3">
      <div class="row">
        <!-- The row I want to move to the very bottom in a mobile view -->
      </div>
      <div class="row">
      </div>
      <div class="row">
      </div>
      <div class="row">
      </div>
    </div>
    <div class="col-lg-9">
      <!-- Content -->
    </div>
  </div>
</div>

Make 1st row two times:

• show one on desktop (using Bootstrap classes d-lg-block d-none) and
• show one on mobile (using Bootstrap classes d-lg-none d-block).

See the snippet below.
