Indicating to play with the other hand natively

I am trying to indicate in my score that the pianist should use the opposite hand by using a hook-shaped bracket. Using a floating barline from the master palette and short horizontal line gave me a pretty good effect, as the screenshot shows. I would like to know if there is a way that you can do this natively, though, without using a hack. If there isn't, then I request that such a feature be added.

Thanks
