A simple Automator service, prompted by a query in another thread.
If you select a list, for example on a web page, and choose this service from the current application’s Services menu, a set of groups, based on the selected list, will be created in the current DT database (initially as children of a date-stamped parent group).
Not lightning fast (a bit faster after the first run) but will signal completion with a Growl notification, if Growl is installed.
To install, unzip and dbl-click on the .workflow file, then Save As (from Automator) to the service name that you prefer.
