During testing, customer created 100+ analytics (tables, graphs, etc.) across S&OP and Demand planning area, and has been using the configuration package to move them from environment to environment. However, at the time of go live, they would like to change all the table ownership to a generic ID (say system admin ID) instead of individuals who created the table for future maintenance.

They are not able to do a mass cleanup in the configuration package before upload. Is there anyway to do this? copy and recreate that number of tables, linkages among tables, and page layouts with a different ID individually would consume a lot of time during cut over.
