\is there an easy way to calculate your total inches / cm lost

Hi everyone,
I've been trying to see if there's a way to get your total inches or centimeters loss the way you can do for the weight.
I can get a report on 'each' measurable points I picked but can't figure out how to get a total (all of the measuring points together).
Does anyone know how or if it's even possible ?

Thanks for the help
