Is there a way to have a function draw a box around an object by finding the objects instance name via a string?

such as:

```auto
function BoxObject(object) {
//code to draw a box around the object
}

```

and then juts have an object with an instance name, like “my\_mc” and then call the function on a keyframe like:

BoxObject(“my\_mc”);
