Hi Anne,
You may have already thought of the workaround but have you considered creating a composite of the Label and Percent of Total like shown below.

If it is something that could be useful to you, here simple table with 2 extra columns to generate the composite labels: you'll see that the formulas are quite simple.
Best,
