Copy project in navigator

[Anonymous]

Can a project in navigator be copied and renamed while still keeping the original project intact?  We have a project in navigator which is being expanded.  We need to copy, rename and renumber project into new project navigator and still keep the original project as a record.  All the project's base drawings will need to be renamed to the new project number.  We want to avoid having to rebuild all the sheets which are already set up in the original project.  Can it be done?

thanks
