Feature Request: Ability to download bill in a more workable format

Would it be possible to add the ability to download my bill in a .csv or .xls(x) format? I'd really like to be able to import my bill into excel, massage the data, and put it in a pivot table.

I'm on a Mobile Share Value plan with my and my wife's families, so splitting bills can be a little complicated. This would let me split costs my own way (and not have the base plan cost lumped in with the primary line).
