There may be a better way to do it using CHTeditor and allowing each page to have different settings. However, if that doesn't work, one option is to do the following
Choose on of the "bottom" pages, Edit Home Layout > Configuration > uncheck the Quicklinks box
Then, use free links instead of quick links in the "bottom right" and "bottom middle" pages. You can then add a widget to the bottom left page.

Hope that works out. It will be tedious setting up the bottom pages using free links but you hopefully have to do it only once. It will however not be easy to edit or swap free links compared to quick links.
