Help!: New Feature Request - Is It Just Me

I have been using the site for a month or two now to log my training and I really like both the "Out And Back" and "Loop" features however there is something between the two that I'd really like which is a "Loop Back" feature. If I've got a route which goes out somewhere, then does a big loop round and then returns home via the same route I took out I'd like to plot the route out, plot the loop round and then hit one button to follow my route out back home from the point where they cross.

To give an example of what I mean I'm planning to do a route on Tuesday which uses windy bridleways (therefore not roads so can't be plotted using the Follow Roads function) for 12 miles between Heathfield and Polegate via Hellingly. When the route gets to Polegate it winds off round a set of roads before ending up back at Hellingly about halfway down the bridleways I've already plotted. Currently the only way to plot the route back to Heathfield is to plot all the same bridleway routes but with the added complexity of trying to avoid the current points on the map. What I'd like to be able to do is to get back to Hellingly and then press one button which works out the intersection and then plots the points back.  You can see this route at http://www.mapmyride.com/ride/united-kingdom/heathfield/425273665 if you're interested.

My only other option at the moment is to export to a GPX file and then edit that manually in notepad (which isn't ideal).
