Friend page: display "Participated Groups" as default

Hello.
1) Navigate to friend's profile page
2) Press on "Groups" tab (because I want to know his "Participated Groups" ).
Result: First I see "Created Groups" and list is empty.
I need to make one more click to see "Participated Groups".

Can you please make "Participated Groups" opens as default when I click on friend's "Groups" tab?

Or may be you can add "All groups" (Created + Participated)?

Thanks.
