Mechanism to refresh the network feeds used in the setup manually via a shortcut

It will be good if there was a shortcut using which we can manually trigger the feed refresh via some Tasker context of a Launcher gesture or even a touch target in the setup itself.

Network refresh includes data like RSS data, web page parsers, Quote, weather updates, ...

Basically this can be used to avoid having an automatically triggered network refresh to get the latest RSS feeds or weather data or Quotes or things like that.
