Widget request

The plugin widget can show some statistics on the web page.
I can display sessions from 7 days, 14 days and 30 days and it´s working fine.
My customer wants to keep graphics the same, but show the total from the whole site lifetime, a number that is available in the admin panel but I cannot select this “lifetime total” in the widget dropbox.
Maybe only add one selection box “replace total with lifetime sessions” so we can select a time frame for graphics and display total sessions in the number below the graphic. A new string can be created for this, to keep things simple and avoid change the graphics. I do not have enough PHP knowledge to change the code myself, but I believe is simple for someone on your side to add this feature. I hope this is simple, not sure.
Can you please provide some feedback if this is possible?
