[thredds] Question - Can dataset scan add more metadata dynamically?

Hi,
We have a use case where we want to add a granule ID (which is the same as the 
file name, but additional tag) in the resulting catalog XML that the client 
side can consume.
Is there a way to do that from the configuration file?

A more general question: can the scan read some of the global attributes in 
NetCDF files, and incorporate in the catalog results?

Thanks for any help.
