Hello Andrey,

Here is the plan I am going to implement:

* There will be a **“Select All / Unselect All” checkbox**.
* When the user clicks **“Select All”**, all displayed numbers will be added to the **“Ready to Activate”** box.
* Users will also have the option to **remove selected numbers** from the box.
* After that, the user can click the **“Next”** button.
* On clicking **“Next”**, all selected numbers will move to the **Confirm Order** section.
* The rest of the process will continue as it is currently working.
* I will also add a **“Ready to Activate”** label above the box, as suggested in the screenshot.
