Ability to sort non-numeric columns in pivot charts by non-alphabetized sorting convention

Currently non-numeric columns on pivot charts are only able to be sorted by A-Z or Z-A for Ideas and Initiatives. It would be helpful if these columns could be sorted in a customized way. For example, if sorting by initiative status, the column order on a pivot chart would not be bound in appearing either A-Z or Z-A, but in a customized way. This could be done through a "drag and drop", or through developing a custom sorting method somewhere in the settings.
