In reply to LukeDclimber:
I doubt we will ever implement something like this. In order for you to record ascents like this you would either have to enter the id's of the routes or we would have to do some fuzzy search for crag names and route names. The latter option would be inaccurate and might actually end up picking up routes that you haven't actually climbed.
With the logbook updates its pretty easy these days to multi select many routes to record ascents. I think you'll just need to take the time to do this.
As Wayne has said, we have the option to export your logbook should you ever want to store this information locally.
