As there are thousands of bus stops and hundreds of bus routes that I am examining, I would like to have a better workflow, but automation is not currently possible. I am hoping that automation *might* be possible once the missing stops and bus routes are added (so that existing stops are members of a route relation), but there are a lot of existing stops that also need updating.  Manual effort won't achieve 100.0 percent accuracy, and the few errors (out of the thousands of edits) should not be a cause for alarm (particularly as you have a process to identify and remedy the situation). Yes, perfection would be nice, but is it a realistic goal?
