Hi Francesco, yes this is one of the areas that I want to work on in v4 - currently there is a Merge command that does what you want but there isn't an icon for it in the UI because I get worried about having 2 buttons with very similar names on them. So to run Merge currently you need to either type in the command name as Karsten writes above or you can set it up on a keyboard shortcut with Merge as the command name part of the shortcut key.

For v4 I'd like to make a new Join function that would have options inside it for something like "Keep segmented" (like how Join currently works) or "Merge segments"... Something like that anyway.
