There are several pathes through old times to reach a certain profile.
Assume Charlemagne. From one single person today there could be 5 different pathes to this old man.
However, you notice that 3 might be questionable because there are no real sources and you want to replace
this old path with a new one. It seems to be impossible.
This should be an important feature for documentation purposes.
There are unforunatly many mistakes in the tree - or let's say - relationships without primary source.
When I try to generate a path to this ancient relative I always get back the "wrong" path
and not the new one I have found out.
I hope you understand my issue. Put a reset-button somewhere.
