This is right in Innovia. Search and select the properties, click Use Checked, click the button Driving Directions and then work the list. , You can juggle the order around to mesh with the realities. This will do up to 20 locations. I have found some drive times to be too long, but that gives you some slack in a schedule. If you really need to optimize go to randmacnally.com and join. Once the properties are on a map (oh, that is another problem ... listing agents not mapping their properties correctly or checking the geocoding that Innovia assigns). you can usually get a pretty good idea of the optimal route options.
You may have to enter addresses manually (or approximations) if the location cannot be found, but that is not too bad if you have any idea about the area.
