link between omnioutliner 3.0 and omnigraffle files

[philippe]

Hi
I have seen in the help that I can link a folder or a file to my OO3 
file
but is that possible to have link with specific graphic  from a 
omnigraffle file ? ( so I can edit the graphic file in omni graffle and 
paste back to OO3 file)

I have tried to use the " reveal in finder" to edit my attached file 
but the "reval in finder" action get the OO3 file and not the 
omnigraffle file.
thanks
philippe
