Can I create CustomShape with VBA for CD? Can I create tool?

Hi!

I don't like some CD command, for example, "Fit text on path". If I am changing aspect ratio for text object and execute this command, the result aspect ratio is different for all chars in text object.

I can write macros, that convert all chars in text string in curves and fit curves on path.

In the future I'd like to move curves along path, and I'll need special tool look like "Pick Tool" in CD. How I can create Tool?

Of course, I can create some custom property to shape object and define GlobalDocument_ShapeMove event. In this event I can determine or I must to move shape along the path or not.

In that case how can I control dotted frame of moving object?

How can I create CustomShape or add custom propery to shape object?

I use CD10 and CD12.
