Playback and notation of a fanned beam?

Dear users and developers,

Is there a handy way to playback of a fanned beam properly?
I think it should be a manual work but throw a question here…
Probably, someone has a sophisticated way to do it.

Any suggestion would be helpful!

Currently, I am trying to make a fanned beam with proper playback as follows, but Dorico does not create a fanned beam:

I resolved the problem as follows:

  1. resetting beaming
  2. creating a fanned beam
