Back to original timing when timewarping

When I am busy warping in the part of a a longer track, the rest of the track just stretchtes from the last warp marker to the endmarker. The reference with the original time is lost.
Is it possible to gowards the end of the track and tell the wave to go back to the origial recorded position?

Of course I could have set a marker on beforehand, but I forgot to do that…
