reuse helps a lot in saving design time,
you can go through the chapter 29 in "padslayout_ref" in your installation docs directory to know about the reuse
you can even go through the MG576756 technote on how to reuse from one design to another design
can you share MG576756 technote file i could not access the support net
I cannot post a technote here since it is not allowed.
you can see the below white paper for more information
