I'm pleased to say that we've now implemented this suggestion. See our news post "Retracing the Same Route Back" for more info.
Thanks for this suggestion - this sounds like a useful feature. It may be that we can amend our Same Route Home feature to enable you to choose whether to plot a path all the way back to the start or only part way. In the meantime, the easiest solution is probably to use the Same Route Home feature to plot a path all the way back to the start and then delete the part you don't want using the Delete Section feature.
Many times we plan linear deviation on a circular route, then we have to come back on same circular route to a specific point and then continue on the loop. Now there is available the complete comeback basic plotting function, but this create the return all the way to the start point. Will be useful to have the possibility to choose the point until the route is returning on the same route. Is like heaving a lasso shape route, with start point anywhere on the loop and we need to have back and forward the linear part of the lasso.
