Currently, Anything > Filter > Control > Combo Box only gives users the ability to add combo boxes to pages in Edit mode, not Page Master mode. This means that users can use the automation to create a bunch of combo box filters automatically but if they want to move them to page master combo boxes, they have to do a bunch of rework and modify variables to do so. Allowing them to select if they want to add them to the page master as part of the automation would avoid this
