Start typing to add the name of your Custodian. If the Custodian does not auto populate below as a previously used name, you can type their name to add them. Simply hit Return or click the "Start Upload" button to begin the upload.

To add the custodian account-wide, you will want to click that option and add in a matching email address.

If you're an Upload Only User, you will need to contact a Project Administrator and ask them to create the custodian for your upload. Once the Custodian is created, it will appear in the list of options.
