I would like this feature, too. I tried to use your standard savings temple and it's a bit of a joke if you need to manually calculate all the fields you provide in there. Try it and lol! I find the "slippery slope" argument silly. You could use that for any new feature request. Embedded Excel sheet worked fine for xOS (it updated the note) but updates did not propogate back to Evernote under Windows (download worked, though).
