Update price book prices in bulk

Is it possible to do an en masse price increase? Say we had all prices cascading down from Standard Price (this is the goal) and wanted an across the board +10% price rise. Is there a way of doing this by a few clicks rather than line by line?

This isn’t currently possible but would be a great addition. I’ve moved this over to the feature requests area, where your idea can be voted for and tracked through to implementation.
