Export all sites to blueprints

I’d like to have an easy way to export all of my Local sites to blueprints for purposes of changing machines (got a new Mac).

Would be great to be able to select all of my sites (or select multiple sites) and be able to right click and select “Save as Blueprint”

Then it would ask for a directory to drop the ZIP files and we’d be in business.

Something that would go well with this is the ability to import multiple blueprints at once (accept multiple selected files), and just walk through confirming the settings on each one individually until they are all processed.
