Archive Programs,Portfolios, Etc.

It would be great if there was a way to archive old programs and portfolios that we are not currently using/doing business with. It would really help keep our system clean and accurate. We have so many old programs that it becomes messy. For example, we have "2015 incremental", "2015 retainer", "2015 investments", etc under one single portfolio. We no longer use the 2015 programs since we are in 2017 now. We still want to be able to see the history of these programs and clients and projects, just want a way to archive them or deactivate them. Would also be nice to have the ability to reactivate them if we need to use them again. Similar to how you can deactivate and reactivate an employee. Would be nice for Admin users to have the ability to "clean up" and audit our information in Workfront.
