   Not that it really matters, but in Airflow 2, we've been successful at 
making them dynamic by subclassing `list` and implementing an override for 
`__iter__()` (as demonstrated in the example).  This could be done in a far 
simpler way, but the example was more representative of the workaround we've 
used in the past.

   > @codecae I think this feature needs some explanation in the UI alert docs 
about how to make it dynamic
   
   I'll try to come up with some simple doc updates to explain how to implement.
