CarTypeWanted question, One specific car listed in TDB, several types show up in activities Options

[ddedicos]

Hi guys,
I recently updated my A&O sub template and tried to make a simple activity with the "Yard" template in Urbanette. I used North 1 and North 2 as source tracks and had Tyson 1 and Tyson 2 as destination tracks. In the TDB, Tyson 1 and 2 have HP and HPMT as the only cars "Wanted" and "Shipped". When I generate the activity, there are gondolas,tanks, and bulkhead flats that are to be spotted on the Tyson tracks! I am using version 4.2.0.12 My question is, how would I have the proper cars available in my source tracks that would match the cars needed in the destination tracks. I understand that North 1 and 2 have "Any" as the type of car that may be assigned to them. Hope this question makes sense?!? Thanx!!
