Hi,

Yes, I know about the "create unique filename" setting. I want to export
the images with the same name always, overwriting the old export if it has
been done earlier. In that kind of scenario the $(VERSION) number would be
nice to be added to the target storage path because I don't want multiple
exports of the same image with a running number in the filename.

I tried this kind of funny approach but the variables do not seem to
support nesting:

Storage path:
* $(FILE_NAME)$($(VERSION/#0/)-_$(VERSION))
Exported image filenames (version 1 is a virtual copy):
* Image$(1-_1).jpg
* Image$(-_0).jpg

As you can see the result was not what was intended. What I was trying
there was that if the $(VERSION) is "0", then it is replaced with empty
string. And then if that result is empty, then use the default instead that
is "_$(VERSION)".
