Creo Label Clean Up

Hi, we have an intern helping with label clean up.

"when I relabeling the “Detailing (MBD/MBE)” section, I found the “Drawing” label has 1,356 conversations (please see attached screenshot) but it’s not on the pre-defined label list. Should it be considered as a valid label in this case?"

In "Creospeak"  are "drawings" distinctly different from "detailed drawings" should I make drawings a predefined label in addition to detailed drawings?
