This has been implemented in the latest version, currently in dev on foundthru.com, will be rolled into upcoming release.
Some notes: The option now correctly prevents multiple selections in the WIDGETS – BUT – there is nothing to stop a user manually typing the additional items into the URL.
However, if you use our canonical URL feature properly then this won’t matter, even if discovered by google bot.
