DOD Banner on SMA/WSA login screen

Question

Since the new splash screen on the login page the login banner appears to be limited to two lines.   Does anyone know a work around for this?
The official DOD banner is:
You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the
following conditions:
-The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations.
-At any time, the USG may inspect and seize data stored on this IS.
-Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG authorized purpose.
-This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy.
-Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details.

Answer 1

Back up all data before proceeding.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
If you want no text in the login window, triple-click anywhere in the line below on this page to select it:
sudo defaults delete /Library/Preferences/com.apple.loginwindow.plist LoginwindowText
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. You'll be prompted for your login password. Nothing will be displayed when you type it. Type carefully and then press return. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. You don't need to post the warning.
If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.
Wait for a new line ending in a dollar sign ($) to appear below what you entered. You can then quit Terminal.
If you want text, enter the command below in the same way. Replace "YourMessageHere" with whatever you want the screen to show.
sudo defaults write /Library/Preferences/com.apple.loginwindow.plist LoginwindowText YourMessageHere
