Is it possible to batch edit multiple instruments in Dorico5?

Can Dorico5 change the MIDI Note length and Velocity values of multiple instruments at once like Dorico3.5?

Welcome to the forum, @Takuma.N. Yes, you can select multiple instruments using the selector at the top left-hand corner of the Key Editor. The changes are explained in e.g. this video:

I did not know that you could edit multiple instruments from Dorico4.
I was very confused because there were no explanations on how to use Dorico in Japanese.
Thank you very much.
