It would be great if each supplier or product had packing lists for required/recommended clothing and equipment.

Some suppliers for example advise to bring rain gear or say you must wear rubber boots for a tour. Rather than adding this information to the description of every item (or sending it to travellers separately) it would be really good if it could be logged in Tourwriter and displayed at the bottom of an itinerary in a combined list (with duplicates removed).

Multiple packing lists would be needed for different seasons (i.e. winter & summer).
