It's not quite clear what you mean. Do you mean, how do you get a scenario to look in a Conquests folder to get graphics etc? Open up the Scenario Properties page in the Editor and add the name of the folder to the box where it asks for them. The best way to do this is to look at the conquest in question in the Editor and do this, copy the name of its folder, and then go back to your scenario and paste the folder. You can add as many as you like as long you separate them with semi-colons.
