Once you have created one record, you can use the Clone feature to create a copy https://ternaus.atlassian.net/wiki/spaces/TERNSup/pages/2405957740/SHaRED+Getting+started#Clone

The clone will have a different unique identifier resulting in a different metadata record. In the cloned record, update any fields that should have different values, for example change the Title on the Data identification tab.

In the “My records” list, the clone option displays next to existing records.
