"Revision clouds" with CorelDRAW...?

I have burnt too much time creating rev clouds for changes required by city/county ordinances requiring annotation of said changes...

Anyone got an "easy button" for what I'm after......?  (Yes...  I'm a CAD guy who could smoke 99% of my ex cad flunkies using Corel, simply because it's incredibly more intuitive and user friendly than any Autodesk product.  \rant    You know...  A REV CLOUD...  Looks like this:

And NO - it doesn't have to have the fancy, Autocad created varying strokes.  Creating a line composed of arc segments (of an adjustable length/depth) is the goal here...

ANYONE......?   Thanks in advance fellas/ladies.  Dave
