How to create a double beamed note.

Hello, I was wondering, if it's at all possible, how to create a double beamed note. I'm not entirely sure what they're actually called. In my case of percussion music, it would be used to emphasize using both hands to play it. In the link is a piece of music that I'm playing that uses a good amount of these and I'm writing out a piece that I want to use these in. Any and all help will be greatly appreciated, thank you!
