When multiple notes are added on an action record, the oldest notepad information will display on the Actions tab of the constituent record. This solution provides more information on how to display the new notepad first.
Only the first Notepad entered will appear on the Notepad Description column on the Actions tab. You can delete the other notepads to leave the one you want to see. You can then re-add the other notepads using their original notepad dates and information.
