Yes, it helps a lot -- Pagebuilder is a remarkable plugin.

No problem building the pages how and where we want them (though we don't yet know how we will obtain a value for the 'destination directory' column).

One problem remains -- it's not something that can be fixed in Pagebuilder, but maybe other pagebuilder users have already done it -- how can we get search.cgi to return links to the Pagebuilder pages instead of the normal LSQL category pages?
