Add (select all) in multiselection options

[Mohamed Selim 24]

Please try to add (select all) function in multiselect mode in web server, that could be beneficial for multiple situations as assigning multiple items to genre, refresh, collections etc

Agreed.  Either ctrl+a or finger/mouse drag.

Yes this is a good idea.
