This dialog box is available from the File > External Content > Hotlinked Module Settings menu item, if you have selected a placed module on the Floor Plan. Its settings are almost identical to those of the Place Module dialog box.
This is a slight variation of the Place Module dialog box, with an additional checkbox allowing you to break the hotlink to the Module.
Break Hotlink of Selected Modules: Check this box to break the Hotlink without clearing the elements that make up a single instance of a Module.
