Galaxy S5 :: How To Disable Notifications From Specific Calendar

So I have 2 calendars, my personal gmail calendar, and my work (exchange) calendar. I like the gmail calendar to have a certain notification sound, and I like the work calendar to use another.

I also use Microsoft's Outlook app for my work email and calendar, and set those notification sounds how I want them.

What happens is if I have a work calendar notification popup, I get the right notification and sound from the Outlook app, but then I also get a notification and wrong sound (it uses the gmail calendar sound) from the Android calendar app.

I know I could just disable the work calendar within the Android calendar app, but I want it in there because I have a widget set up that shows my agenda from both my personal and work calendars. If I removed the work calendar, it would leave the widget.

So I don't know if all that was confusing or not, but here is what I want: Personal gmail account calendar notifications from Android calendar appWork exchange account calendar notifications from Outlook calendar app. Both personal gmail calendar and exchange calendar set up in Android calendar app so I can see them both in my agenda widget

What I don't want is when a work event occurs, is to get 2 notifications about it using 2 different notification sounds. I only want to be notified from the Outlook calendar app.
