Sometime, when I plan a flight, I consider for some legs, multiple choices. I.e. imagine my route is from A to F.
On option is A - B - F, another is A - C - D - F. The effective choice may depend, once in flight, by weather condition, ATC clearance and more. It would be nice if, in planning mode, I could enter, in the some route, both options and, in navigation mode, through a switch, I could activate one branch or the other. Today, without this function, I prepare two routes: A - B -F and A - C - D - F. If I decide to switch to route A - C- D - F, I have to click the Skydemon menu, click on Route, then select the new route.

We have considered this many times, and we always decide that the small benefit introduced (not having to go to Route -> Open -> Select) is massively outweighed by the various user interface bits and pieces we would have to introduce to make such a feature possible, and to make it discoverable enough to benefit lots of users.
