For platform-to-platform environments, I nest all shared tables under a specially named Schema with a prefix of DS-. For example, my schema name could be ds-mfgschema. This is a 'flag' that any tables nested under this schema are being delta shared with others. Of course, you could do this same naming convention at the Catalog level as well (or even at the table level). But I find doing this convention at the schema level simple and effective.
