$ionicPopover position


I’m using $ionicPopover to show a contextual menu : http://play.ionic.io/app/86ebfa97108f
My problem is I can have quite high items and the popover position is calculated from the bottom of the item which leads to quite strange popover position :frowning:

Do anybody know a way to customize the popover position ?
It would be nice if it were calculated from the center of the item (top+height/2) or from the icon position…
