How Can I Position Captions in Camtasia Studio 9?

Captions are not manually moveable in CS8 either.  However, in the formatting section (font type, size, color, etc.) there is a dropdown box that allows positioning all captions to the left, center, or right.

Dubie suggested using a callout.  I didn't want to spend much time on this but here are two images that show the difference between a callout (top) and a caption (bottom).  the background was changed to show that they look remarkably alike.  The major differences SEEM to be that a callout has square corners instead of rounded, can be moved to any position, much more control over formatting.  Captions have an index, of sorts and can be moved to three positions.
