This tool sets the name (and keeps it linked to the assembly name) for all elements contained in the assembly.
This tool works in two modes:
Only elements that match the name of the Assembly
it only changes the name part of the child elements that contain the same name as the parent assembly, it leaves the others unchanged.
All children use numbering items
while, in this case, it will change the name of all the elements by connecting it to that of the parent and completing it with the rules set in the dialog box.
