Agents and Scanners for TV Shows

Hey everyone,
I recently started fiddling around with my Lib sorting and found a few helpful how-tos. Somehow everyone keeps talking about setting an agent and a scanner for TV Show libraries, however I only have the option to set an agent. The scanner selection does not appear for TV Shows, only for Movies. IS this a feature or am I doing things wrong?
Thanks in advance!

You set the agent in the main server settings and then specify it when you create the library (or edit the library)

There is only 1 scanner provided by Plex for TV Shows so you aren’t even given an option. I believe if you add a custom scanner, then the option to choose which one you want to use will be shown.
