HSDL Migrating Templates

Summary

Cannot import existing Templates

Content

We need to make some changes to a number of our custom HSDL templates that we have created in the past.  Is there anyway we can import these templates using the same layout code and name? It seems the Import window forces you to create a new code and name.  We we don't want to create a new Template Layout code or Name when importing, because we have these templates referenced in our BI reports as links to download the template. 

Also we are trying to avoid manually making these changes on every environment.
