Alarms

I am setting up alarms in DC, I can get them to display the messages and everything as I intend. I have alarms set up in my ECU and I am just sending those status to the dash to trigger the alarms. However, I am not certain on how to use the alarm acknowledge function. My question is in relation to the way the standard non display creator allows you to acknowledge the alarm to hide or remove the warning for a certain amount of time.
Do I need to create the alarm in Dash Manager first and then send a new channel through DC to display on the dash? this just seems like a few extra steps that could be handled in DC directly.
