RibbonGroup Selection Behavior

Hello,

I'm looking to determine if this behavior is possible in Smart GWT 4.1:

I have 2 RibbonGroups on a RibbonBar. In the first group I would like the last selected icon to remain "selected".

Any time I click an icon in group 2, I do not want it to appear "selected" (i.e.: i just want to click on it and process the associated handler normally). I could with 1 IconButton being selectes in each group but don't want it to change the selected icon in group 1.

Any advice would be greatly appreciated.
