How to set "Caption Placement" to "Follow Diagram" as default?

Hello,

I would like to know how I can set the default value for “Caption Placement” for an Activity in an Activity Diagram? Every time I drag an Activity in the diagram I have to change this parameter to “Follow Diagram” manually.

And the “Set as Default” button in the font section of the Formats dialog changes only the font although the “Caption Placement” parameter is in the same section.

Maybe one of you can help me with this issue.

Best regards,
Thomas

This seems to be how to do it for certain shapes:

  1. Select Window > Project Options… from the toolbar.
  2. In the Project Options window, select the Diagramming category, check an option out of Caption Placement section under the Appearance tab.

It would be helpful if we could change the default caption placement for labels in a sequence diagram (for example, to Middle Left). It would be even better if I could set requests to Middle Left and responses to Middle Right.
