Nothing on this one. But, if you wish to have different icons within the same Fence. You should try those tabs available in Fences 6.
From what I understand, those icons needed to be auto-arranged, if not, Fences will have issue on multiple screens system where those Fences will jump from monitor to monitor with different resolutions when those monitor get connected/disconnected. Those Fences will need to rearrange and resize themself properly when those monitor connected/disconnected and changing resolution to suit which ever monitor/s still active. If it is not auto arrange, Fences will have hard time to track which icons stay where and some Fences can not be resize to make sure the icons stay where they are. I think that will make it a lot more messy.
