Is there any way to create a single note with an extended beam?

 

forgive the ascii artwork, but something that looks like this:

I've found one workaround, which is:

 

turn on beaming options>beams over rests.

then drag the rests off of the page (using the edit frame dialog in speedy).

 

however, this is a pain, because it turns on beam over rests for the whole document, meaning that each one has to be manually edited.

 

I've also considered putting the beam in as a shape, but that is also a pain.
