Is it possible to use the AnVIL package to write to a "Workspace Data" table? avtable has a corresponding function avtable_import to write to a data table, but avdata appears to be read-only with no corresponding import function. I would really like to be able to write to this table programmatically rather than by uploading a TSV using the web interface.

I think this should be possible; I've opened an issue on the AnVIL package.
