How can I use the Library to create a Master Aero?

There are the two ways to use the Library to make a Master Aero:

• Library Template > Add Master Aero - you would go back to the Library to create each new Master Aero. All of the Master Aeros created this way stay attached to the Library and are automatically updated when the Library Template is updated. 
• Library Template > Clone > Aero Template > Add Master Aero - You would go back to the cloned Aero Template to create each new Master Aero. Master Aeros created this way are not updated when the original Library Template is updated.
