Ability to type in or paste contacts when resending campaign

Why do you have to "fix" things that aren't broken? 100% of what we do via Constant Contact is sending instructions to new clients. We do that by resending a campaign to a specific new email address. Now you have taken that option away so instead of a simple and fast process that I have used for years, I now have to add that person to a list, delete anyone else from that list, and then go back to the campaign and resend. What used to take about 3 steps now takes many more than that. WHY???
