Here are what the logs currently look like in the console when I use the "Run PyAEDT Script" button in AEDT:

As you can see, I'm getting a bunch of log messages that aren't relevant to the users of my script, and each message from AEDT is getting logged twice: once with the PyAEDT INFO:
format, and once with the [timestamp] - INFO -
format.
I tried this:
from ansys.aedt.core.aedt_logger import pyaedt_logger
pyaedt_logger.level = logging.DEBUG
...but it had no effect.
