the current implemenation does no grouping of signals. maybe you already know this, but it's not enough to just insert a node at the right position - it needs to be part of the way. it's possible that you can insert several nodes (as part of a way) on the same coordinate, although that would lead to segment with length zero. you will have to see if that breaks something.
