Change type of stem (New workaround?)

I would like to share the method that I use to change default stems to any type of stem in a very simple way. The only condition is that you don’t need to use some of the default tremolo stems. The method consists in changing the default symbol for one-note tremolos or buzz roll (Engrave>Music Symbols>Combining tremolo # or Buzz roll) to any stem or symbol you like. You have to align the stem at the centre to avoid a doubled stem:

This method does not allow define a stem that can be flipped, though. I hope it will be helpful to somebody.
By the way, I would like to ask for this feature as default… Being able to apply the magnificent stems in bravura to any stem would be great!

This is indeed very useful!

Moltes gràcies company!
