Also, in similar vein: label modifier

There's transform/commonMetadata, which adds labels and annotations .. What kind of modifications would you want to do to labels? Changing particular labels, or adding / subtracting from the set of labels?

Example 1

Example 2

Given a selector, append a new label.
