Time limits
 

In pre-made scenarios and campaign is it possible to change the number of turns?

Yes - use ScenHack utility

Campaigns are a bit tricky as you need to extract the scenarios to change the turns they are given then rebuild the campaigns but the number of scenario turns can be changed with either Scenhack or the in-game editor just load the scenario with the editor, press deploy then change the turns using the button that shows the clock face. With Scenhack you click on the "Scenario" button that is under battle Date and change the turns then re-save
