Feature Request: a real alarm for some -not all- due items as real calendar alarms

Feature Request: a real alarm for some -not all- due items as real calendar alarms:

1.) real alarm: something is ringing or knocking.
2.) not all due items: only necessary (and realistic) some some special due items.
3.) as real calendar alarms: Now they are just visual entries in the calendar which is fine, but some of us probably want an audio signal as well.

As for now I’m using this workaround with Keyboard Maestro and the Due app, which some colleague of us came up with, but it is unreliable and chunky.
