All I did was pull the code from ctmail return selected and added it to a working copy of ctmail mod for patch 2.0. And it worked. I'm not maintaining this though, if someone wants to upload another update they can.
You should be able to add updates to this project.
If the author of return selected wishes to take this over let me know.
i'm not the original author of return selected.
thanks
To return selected, check off the items you want to return. Then click return select button. If you want to see the status click the check box at the upper right.
