My first growl on the clarinet

[beppe]

I am looking for the best way to notate the growling effect (on the clarinet), I thought there was something in Dorico but couldn’t find anything.
Thanks in advance.

This is a trumpet part not clarinet, but I usually just use “Growl.” If it’s for a passage, using a playing technique for the word “growl” followed by a line would be fine too.
