We are in the process of getting ready to transition our accession records to ArchivesSpace and have three separate repositories set up.  Each repository uses the user defined fields in the accession records in a slightly different way and would like to be able to use different labels for them to reflect the actual information that is stored in these fields.  This is how we have Archivist's Toolkit set up.  While we have found the documentation about how to edit the en.yml file, we have not been able to figure out how to or whether we can customize these edits for each repository.  Is this currently possible and, if so, how would we go about this?
