How do I animate an outline of a rectangle?

Question

I’m in the process of creating some basic learning demos for staff and I’m trying to apply an animation where the outline of a rectangle/box appears as if it’s been drawn over the area where I’m showcasing (similar to what you see in other training demos for how to use captivate).  Haven’t been able to come across how I would achieve this and any help is much appreciated! Thanks

The only way I have been able to create such an effect is with four separate lines configured to line up to form a rectangle. The first line is set to appear immediately and with the StretchFromLeft effect. Each subsequent line is delayed in appearance until the previous line has been fully formed. Then use the appropriate StretchFromTop, Right, Bottom effect depending on which line you want to appear next. Sounds complicated but this took me more time to write this than to create it. Here's a screen capture of what my layout and timeline look like. Once you have an example of this it's easy to copy and paste elsewhere.
