Use-case actor (stick figure), request additonal/selectable graphic
In real use-case diagrams, the Actors are not always People, they are often some external system. I request an option to represent a non-human actor, anything other than a stick-figure.
Yep, a simple rectangle with <<actor>> and the actor's name is a current element in system use cases!

You are missing a point in UML diagrams. Actor is not a human - it can be anything. 20 years back there were no well integrated systems, so human interaction took the major place.
But idea is: Actor is client/service/user/app. Is a standard from UML. Let's not transform it into power-point-presentation.
