Possible to adjust icon graph speed scale?

Hi there, i was wondering if its possible to adjust the notification icons graph scale?

Ive noticed for last couple years that no matter what sort of speed of connection of down or uploading the graph shown on the icon is pretty much always maxed. Even though it can show a full range graph, anything over a 1999’s dsl 500k line will max the graph and makes the full range ability a waste of time.

It would be handy if able to adjust at what usage/speed each mark on the graph lights or to set what the connection speed is so it isnt sitting maxed at anything over dialup speeds.

Is this possible atm to adjust this scale at all?

Thanks for look, Greg.
