Labels with an expression for master item measure in Pie Chart

Like in QS Native Pie Chart, is it possible to see the label with an expression for the measure (master item)?

Actualy, i think there is just the name of the measure (with simple text) and not the measure label of the master item.

It is realy useful for exemple if the measure concern only sales of the last selected year. If the last selected year is 2021, it is better to see « Sales 2021 » using an expression (like 'Sales '& max (year) ) than the name of the measure « Sales of the last year ».

(In VL Line Chart, the label with expression appears only for the selected measure but not on the differents alternatives measures.)

Thanks
