Exclude preceding text from label

When labeling things such as presets, it would be helpful to have a special character that effectively "excludes" or "hides" any text before that character when used for Direct Select and/or Magic Sheets.

For example, I might have detailed labels so when just viewing the preset or color palettes so I know specifically what it impacts, but when it comes to using it on a magic sheet that detailed label might be too verbose, and I simply need the color name, or position, etc.

I am imagining something like the double-pipe || we use for a line break, but maybe !! double bang (exclamation point) or something similar?
