Rename drawing with prefix-Animate 3

On Mac OS 10.8.3

On Timeline - select multiple frames on timeline to rename w/prefix.

Choose from Drawing Menu - Rename Drawing with Prefix…

Dialogue box does not open. Cannot rename a range of frames with prefix.

Rename Drawing…command DOES open Dialogue box.
But this does not help me rename multiple frames at one go.

Is this a “bug”?

Are you sure it’s not renaming the drawings? You need to look at the Xsheet to verify since you cannot see the drawing’s cel labels in the timeline view.

Note that this is NOT meant to rename element columns but rather the drawing cel labels of drawings in element columns.
