How to re-position elements on Aalborg Theme and 3-column river activity?

I am using Aalborg Theme and 3-column river activity.

My current configuration,
Right-colum
1. On the top    : elgg-owner-block elgg-module <it has links for blog, file, page, etc>
2. In the middle : A profile picture, welcome message
3. At the bottom : elgg-menu elgg-menu-page elgg-menu-page-default <it is the links to edit profile, avatar, etc.>

I want to rearrange this-right column, and I want to achieve the following sequence,
1. I want to move the top-block <elgg-owner-block elgg-module> from right column to left.

And Right-column should just take the space as:
1. On the top:  A profile pic, welcome etc.
2. In the middle : A profile picture, welcome message

Please note, 3-column river activity allows some rearrangements of elements, but, I could not do this in the admin panel. Thank you for your time. Bests.
