label sorting

[bpgs5316]

First of all, appreciate for your tool.

I wonder how to sort the labels.
As below issues, I customize the label names by using a json file.
I have more than 30 labels, therefore I have to arrange them well so that I can see them intuitively.
I changed them in id order but it doesn't work.
How can I sort the labels in the order that I want?

Thanks again.
