Sound "Brass" in the MeseScore 4 Mixer

In MeseScore3, I used "Brass Set" or "Brass 2" from the sound menu of the Mixer. In MeseScore4, I see an individual instrument from the Muse Sounds/Brass list , like Bass Trombone, Cimbasso, Horn in F, etc. but can't locate such general sets of brass sounds. Likewise, I see difficulty in finding "Strings" sets from the Muse Strings list.
In MuseScore4, do we need to specify each individual instrument in the sheet and allocate the sound each by each? Or, is there any simple way to assign a general sound sets as default, like "Brass Set" or "Brass 2", which was easily working and convenient for non-professional users?
