Logbook: Hide Automaton Reloads

When an automaton is edited and saved, all automatons are reloaded. (Or so is my understanding.) This creates Logbook entries for every automaton, and long lists of these automatons can get in the way of seeing relevant Logbook entries.

The Logbook integration has features for filtering included and excluded entries by integration, but it does not contain a feature for filtering by the source of the entry.

It would be very useful to filter by the source of the Logbook entry, such as if it was created by a automaton reload. These reloads seem to be easily noted by the fact the Logbook does not list a source of the entry like it does with user-triggered events, Home Assistant Cloud, time, etc.
