Unfortunately there is not an option to add attributes to the generated node (i.e. Cell) in those events. You could change the Value to be exported in the ElementExporting event or add an additional nodes when the ElementExported event is raised.
Thanks for the reply, could you please point me in the direction of an example that adding additional info into the cell, I can wrapper things with additional nodes and then post-process them once they're XML. I've tried using the sample code on the telerik page but it didn't seem to have the desired effect when exporting to Excel ML.

You could check this online demo together with this and this help articles showing how you could change the default export.
