thanks, good advice
I always just make them more by click many times "Add sending army" button in "Map" tab
do you think that new cloned tasks should have "Active" set to false after cloning? so, to send it, you will just need to set Active true for them,
under right mouse button "Clone" and then "Set active true"
and of course you will be able to clone many selected tasks
do you think that after "Clone" click there should be a window with number of how many clones should be created? 1 - N ? and OK/Cancel button
