Copy / Paste to active Design Option

[JaredBanks]

When I'm copying elements between files/design options, I want the ability to select "copy to active Design Option." 

When I'm copying from project A to project B and those elements are on a Design Option that doesn't exist in project B, project B creates the missing Design Option—and keeps it hidden.

I want the option to create the design option AND show it, create the design option AND keep it hidden, OR paste elements to the active Design Option.

I would have assumed it would default to main model ( if the DO doesn't exist ) - with the option to paste to [select DO or new DO]
