It would be helpful if I had the ability to add an existing package with all its components into another package. Our team utilizes the package functionality significantly and we have noticed there are packages with components that we would like to add to a larger package with additional components. Instead of needing to add each of these packaged components individually, it would save time and effort to pick up the existing component grouping (package) to add into my new package.

For example: 

Package A - Item 1, Item 2
Package B - Item 3, Item 4

Package C - Package A(Item 1, Item 2), Item 5, Item 6
Package D - Package B(Item 3, Item 4), Item 7, Item 8

Package E - Package C, Package D(Items 1,2,3,4,5,6,7,8)
