Ability to view aggregated savings

Would love the ability to view aggregated total cost savings (vs. ICE) by vehicle for the year, or given time period.  Similarly to how we can view total savings on a monthly basis now, but summed up on a yearly basis, or over the lifetime of Tesla ownership.  This is a very useful bit of info to have, as it not only helps in my own cost analysis, but also is a good statistic to throw out to others when convincing them to move to an EV.
