PROBLEM
To get the Project Wizard to accept a user-defined datum, you need to store it with an empty coverage and then reference it with the wizard option 'Project my data to match existing data'.
The datums list is hard-coded.
Note:
If later projecting needs a different user-defined datum, modify the prj.adf file located under the empty coverage's folder. You can use a text editor for this.
