When editing my magic sheet, I would like to select a group of instruments without selecting the underlying objects. Specifically, I have the pipes the instruments are on shown as lines grouped together. Whenever I select any group of instruments where one of these pipes (in the pipe group) is wholly within the selection box, the entire pipe group gets selected. I tried shift-click to deselect it, but that only adds to a selection, not deletes from it. Is there any way to lock a group so it can't be selected? How can I select these instruments other than by clicking them one-by-one? Is there a way to not select the entire group, just because an object within that group falls within the selection range? It's common to use layers for something like this, but I don't see anything like that.
