Hi @RKan, I have had a look in the most likely places in the scripting API, but couldn't find anything. 😞
It might be possible to script a custom package function. Collecting linked files is easy enough in most cases, collecting fonts is possibly equally easy if we can get the path to them (I don't remember if this info is available to scripts). And making the report is a matter of collecting all the data from the document and outputting to text file—this may or may not be able to include all the info that the native package command does depending on what the scripting API has access to. It would be a fair amount of work for someone.
