insert picture into Aux / Stock variable?

[kleemax]

Is there a way to insert a picture into auxilliary and/or stock variables?
I know it should be possible for comment fields. But I would need it for variables as well.
E.g. if I have a stock of cars, I would like to use some picture that shows cars.
If this is possible it would also be nice to know which picture formats are supported (only raster such as jpg, or also vector formats such as SVG, Windows-enhanced Metafile, pdf, PICT,...,) and whether this differs between Mac and Windows versions of Vensim

It's not currently possible, but I agree that it would be nice. I'll ticket the feature request.
