On a wholesale menu page (/admin/menus/wholesale/<menu id>) the clone dialog has two extra controls: Filter kitchen location narrows the list, and Select wholesale menus lets you tick one or more named wholesale menus (shown as "Menu name (Kitchen)") as targets - you must select at least one menu or nothing is cloned. Sprwt then copies the current date's meals of this wholesale menu to each selected wholesale menu on every retail/wholesale fulfilment date in the range, with the same keep-ordered / remove-unordered / add-missing rules.
