The index number should be a property as well.
Sure, attaching one of the radio button's extended prperties, value changes based on user's input. Index changes as well, everything is dynamic except the objecttype is Radiobutton.
ACtually, ALL properties would be more useful than just the Extended properties. When searching for and identifying an object, there could be other properties of the object that can be used. FindChild and NameMapping don't only have to be restricted to the Extended Properties.
AlexKaras has a good suggestion as well. For some of our work, we use that approach, find a desired row by some other text and then target the Cell contents in that row.
