This question keeps shifting it's targets!
How about we suggest some methods and you pull those apart?
On any TomTom you can save upto 48 addresses as "Favourites". You can view those on the map (as yellow stars) and you can poke your finger at any one and say "Navigate there". All models will calculate a route to one of them "via" another one. All the new models will let you have 3 or 4 of these "via" points.
On any TomTom you can do exactly the same thing but save the locations as "POIs" in your own POI categories instead, so you could have one for Family, one for business deliveries, one for whatever else...
On most of the older mid or high end TomToms you also had itinerary planning, where you could enter upto 48 addresses (or use previously stored Favourites or POIs and sort them into your own order to visit. Each one could be defined as a destination or a "via" point. Once each one has been visited the unit automatically moves onto the next.
Do any of those describe what you are looking for?
