How to move the inset column widgets

Hello,
I am trying to move the inset column widgets (left column) on the pages to left of the text content. How do I achieve this? Right now it is on the left of the featured image. I'd like it to be on the left of the content.

Please see screenshot. Pls advice.

Thank you.

Hi,

Unfortunately, except custom css it requires theme files modifications (layout structure) which is beyond our technical support.
