Multiple Calendars & Upcoming Events

[Eq4bits]

I have multiple Calendars and have some of them set for displaying in Upcoming Events and have my 'events' grouped by date. My question is: Is there anyway to determine the 'order' the events display?
Example:

07-07-2015: Calendar 2 event, Calendar 5 event, Calendar 5 event, Calendar 6 event


right now it's displaying as:
07-07-2015: Calendar 5 event, Calendar 2 event, Calendar 6 event, Calendar 5 event.

I *know* there's a way because I had this issue in the past, but I've forgotten how I fixed it. (yes i did a search of this forum for 'Upcoming Events' but I didn't see the issue addressed in any of the results)

--------------- Added [DATE]1436195017[/DATE] at [TIME]1436195017[/TIME] ---------------

anyone?
