I see that something like this has been requested before, but it’s been a year without any votes or comments so I figured I’d submit a new request.
WhenTasker, Kustom apps and similar tools attempt to get the next system alarm, they often end up grabbing some “pseudo” alarm that was internally set in a non-alarm clock app (for example Tasker) for time sensitive tasks. This breaks automations and I’ve found no feasible workaround.
And so it’d be really useful to be able to differentiate Sleep as Android alarms from any other alarm
