How to add the trial to my admin console for users to test?

[M-L]

Is it possible to add the trial license to the admin console to then create groups and add users to the group, to see the admin tasks?  

I need to make sure that should a user go on holiday the workflow does not stop with them. Perhaps an admin can push the workflow to another user?

That we have a global view of the documents for auditing. 

Is it possible to stop deletion of documents by employees.

Thank you
