Move all windows from one page to another?

Currently, I mainly use DesktopSize 1x5 without switching to 2x2 because the app’s windows of pages 0-2 and 0-3 are not there on pages 1-0 and 1-1 in DesktopSize 2x2. How to move them when I click on my Desk 2x2 button?

For example, all windows in 0-2 move to 1-0. (click screenshot link)

Note: There is a similar question (2008), still valid or things can be done simpler?

Not to spend too much time figuring the code lines, I made it practical by doing it manually. Changed the DesktopSize 1x5 to 2x4 and manually move the apps and windows that are needed on pages 1-0 and 1-1. The main purpose of DesktopSize 2x2 is the mouse scroll feature which allows gliding from one page to another. It is similar to having a large paper sheet.
