Creating a 1945 traffic layer in TMO 2.0
 

Stayed in this evening, tired.Fooling around with the ME and had a thought.I would like to make it where the campaign layer Jap_Convoys_44b ends around Feb 28 1945 and create an 1945A campaign layer.Now I know how to create one but how I do make it so that it shows up in campaign? As in the 44b convoy layer ends at desired time and traffic from the new layer shows up? Thanks in advance.
