Jobs can be organized into subfolders.  While we don't give direct ability in the UI for this yet, it si supported and UI support is coming later.\\
\\
In your CrushFTP folder, jobs folder, make a folder named "QA" or "test".\\
\\
Now you can just move the folders into this folder to have them grouped as such.  Or in the UI, rename your job from "My Job" to "QA/My Job" and it will be moved into the QA folder.

This allows filtering for QA jobs by typing "QA/" on the main job list too.
