When one creates a new appeal mailing in Altru they may want to use an existing mailing from a previous appeal. One will click on the drop down arrows next to the desired appeal and see "Copy" with a drop down option and copy without a drop down option. The copy with a drop down option allows one to copy that mailing to a different appeal. If one chooses to copy an appeal mailing to a different appeal they will notice that the appeal mailing did not copy and the option to copy to different appeal mailing is now gone for all appeal mailings.
