In attempting to remove some NFS_Exports I attempted to Define NFS_Export I wanted to delete "by searching for an existing NFS_Export" but noticed there were no built-in filters or finders for NFS_Exports. I can create ones I need but it made me wondered if there was some reason they didn't exist ... it just seemed odd.
Generally filters/finders are added based on their usage in sample workflows. It may be possible thet some of the objects does not have corresponding filter/finders if it is not used in sample workflows.
Preferably all the dictionary objects should have basic filter/fiders we can take this as RFE for next release.
