I have a lot of charts that use a similar or identical filter, and some that frequently use a field for metrics that needs to be renamed or a different field used.

Is there a way to migrate those charts in bulk, either mapping something in the dataset or charts. These sorts of migrations don't come up often and most concepts we try and model in the underlying data, so changes in implementation don't effect charts. When they do happen it really is painful though as the only option I can figure out is click-ops changing every chart by hand.
