change the duration of multiple notes

Hi,

I discover with a great pleasure museScore and I'm impressed by the level of functionality ....! congratulation ..!
Testing the flexibility of the user interface to enter notes I can't find a way to chane the duration of multiple notes at the same time. I've tried to selecy 2 notes(Quarter) then click on Eighth button or right click to get additional menu, but no way. I can only change 1 note by one note.
Is their a way ?

Thanks for your support and this great dev

Regards
