One thing I wish I could do though is use duplicate values in the config as a way to group different values in a chart. I could certainly get around this by adding fields to object and populating with "groupby" values that I'd want to use, but being able to do so in Report Builder would allow for faster, more ad hoc report customizations.
One example I've run into, pictured below, is reporting for surveys (from a custom SFDC object we sync responses to). We send several surveys to our customers, and I would like to report on responses by on product. But since each of our products has mulitple surveys associated to them, the only way I can do so is to create a new field that I want to use as the "By:" field and populate via rules. This sort of get wonky in between rule runs, but for the most part works. But I think being able to duplicate Aliases would keep the report from having "stale" periods between rule runs.
