You can set Library Manager options so that it operates with your preference settings so yo do not have to re-enter them every time you run an export or an import. For example, you can set the Library Manager to run the DiffManager every time you do an import. (Most of the options can only be set through the Options settings; there is no prompt for them.) After the options are set, the selections are maintained each time you run the Library Manager (if you are using it as the same operating system user).
