Can I add a value that does not exist from my feature to symbolize against?

[Reynaldde_Castro]

I have a hosted feature that is often updated.  All possible values do not exist at the time of creation.  How can I symbolize for values that do not exist from the attribute table?  Are there plans to allow users to add values to the list of values?

I solved my own problem by changing attribute values so that they would appear as I build the legend.  I changed them back after creating the legend I needed.  There has to be a better way.

Did an easier way get found? How do you add a new coded value to a feature service that will appear as a drop down option?
