You can achieve this with the data source by creating an expression, and
referencing the values of the ifHighSpeed or ifSpeed constants.

All of the constants (i.e. values in the strings.properties files) are
available in the expression context and are prefixed with the attribute
label.

See the attached screenshot for an example.

Best,
Jesse
