Global Data Colors

I would like the option to set global data colors for my reports based on a specific field within the data, that will impact all charts using that field.

For example, in our current data set we have a field 'Customer'. Each customer is assigned their own unique color that corresponds to our other documentation, to make charts easier to interpret.

Currently, I have to set the 'data colors' options for every single chart that uses the 'Customer' field. Whenever a new customer appears in our data set, I have to modify the data colors for multiple charts individually.

I would like the option to be able to set data colors for this field on a report-level basis.
