I refer to the following post: http://wireframesketcher.com/forum/topic/31016/feature_enhancement?p2

AFAIK, this feature is not available in the latest version of the mighty WireframeSketcher. Can you confirm?

If it is not yet available, it would be nice to have this feature as a simple option in the existing checkbox widget.

Thank you.

Grégoire, I confirm, this is not yet available. This feature is on my todo list and I added your vote to it.
