How to change sub nav default?

Hello,

I have installed Events Manager on BuddyPress. In the member admin area, I have a naigation for Events, under which I have sub menu for “My Evemts” and “Events I’m Attending”. When I click on Events, the first screen I see is “My Events”. I would like to change that default to “Events I’m Attending”. How do I change the default sub menu?

Thank you,

Ray
