Local Beta - Blueprints and Duplicating Sites


I am using Local Beta 5.0.6+976 on a Mac.

Is it possible to manage (delete/edit the underlying site) the blueprints or duplicate/clone existing sites?

Thanks in advance.

I exported a site and tried importing it.

Gave a different unique site name and it says:

Uh-oh! Unable to import site.
Error: dest already exists.

Found the option to delete blueprints in Local’s Preferences.
