It would be nice if we can set a constant color/pattern to a value when creating a chart. We would often use the same value in different graph options and I always have to copy the color that we've set to a certain value from a previous graph to make it constant.  It would be nice if we can set that values color constant whenever we'll be using it.

Example:

Table: Sales table

Salesperson: James, John, Jessica

Bar graph: count of sales by salesperson (James - blue, Jessica - green, John - yellow). 

*if I create another bar graph by salesperson, I would like to have an option to use the same color set of each value instead of going back to the previous graph and checking what I used.
