Starting location of activity. Options

[Old Geaser]

I have been making a few activities using Activity Generator for my own use. Have been doing pretty well. I have printed the manual and have studied it. There is one thing I cannot figure out. I like switching and do not really care to Travel great distances.

I am trying to make act's that start in a city and have the pu and so in the same area. I do not mind traveling a short distance. I just made a 3 page act that all pu and so are in Zanesville and Zan Sub. It did great. It has 22 so and pu. Problem is it starts in Marietta interchange yard. A long way from Zan.

I made another for McConelsville area. The starting place is Byesville.

Where am I going wrong? As I remember in the Source Tracks, I checked Zans. and Zan sub. What do I check to Start somewhere in Zans and do the work in Zans and Zan Sub? Any help would be appreciated. Thanks
