As far as I know, to create such buttoms you have to use Origin Professional Edition, that is more expensive
I deal with simple, square, grey buttoms that appear when you enable the "Buttom up" event on the "Script, Run after" property of an object (object.script), and do some pretty things...The only commands that allow you to deal with data grouping are "layer -g", to group all of them in the current layer, or "layer -gu", to ungroup all. Nothing to do with that you need. Yes, this is something that should be improved in new versions of Origin...
