driving a second route during the same trip

What I was trying to do:

driving a second route during the same trip

What I expected to happen:

seeing the progress of my second route (or the combined progress of both routes)

What actually happened:

i see the progress of the second routes on the distance of both routes

Note1 : we either want to show the progress of both routes (If I add another one, we include the points intercepted of the first one) OR we just include in the denominator the points of the second route.

Note 2: After completion of the trip, the percentage in the route event is shown correctly : just for this route.

See screen shot after completion of the second route. The other 37% not completed are essentially the points of my first route.
