It seems that the complete picture of what is being suggested here is the ability to have "layers" in a single routefile whereby each layer presents another route, and the start/endpoints of those routes are shared so that dragging a shared point changes two or more routes that share that particular waypoint.
I compare this to the layers in CAD software, or in image software such as adobe photoshop, or infinity.
each layer could have its own colors, toolbox setting (avoid highways...) etc....
and each layer could have its own name like the tab pages in excel.
Giving focus to the base layer would give route statistics covering all layers, focusing on another layer would give the stats for that particular layer.
an option to import an existing route in a layer, and to explode the layers of one routefile in individual routes could be nice?
