Stack two columns side-by-side under another column?

I have two main columns side by side in a region (image to the left, text to the right). Within that text area, I want to have a top text stretch across two smaller sub-columns, with one text on the left and an image beside it on the right. Photo provided, I'd like to move the image to replace the "read more" text link. But dragging and dropping, I can only get the icon image area to be below the bullet text or in a separate column from both text areas.
