Is there a way to build a viewTemplate for none-existing transclusions?

[Jan]

Hi!
Is there a way to build a viewTemplate for replacing none-existing
transclusions with a template?
For my dialogue-editor (storywriting.tiddlyspot.com) I would like to
replace {{non-existing}} by the title of the non-existing transclusion,
preferably in small caps.
Could there be a way to get this working? Or would it be necessary to
modify the transclude.js widget.

Thanks for help
Jan

...I think this shows the purpose more clear: I would need something like the emptyMessage in the ListWidget...
It would be good if this emptyMessage could be based on the tags or the type of the Tiddler containing the transclusion which does not exist.
