Adding extra user inputs for Alarm Data

Hi all,

Is there any way to add extra columns and have user input data into it for alarm data?

There is the acknowledge notes, but I want to add another column for when the alarm is cleared, for user to input what really happened and what steps were taken, for example.

Is it a good idea to create an alarm associated data, leave it blank and update the row as needed, or creating another table to link the alarm data is better?
