How to get no end before 1945

[Ekaton]

I want to create a scenario that pretty much avoids the 1944 test, I’d like for it to continue until the Fall of Berlin and see how long I can hold, even against hopeless odds. I took the no sudden death scenario and essentially gave the enemy a lot of bonus VP points and lowered my watermark so that it currently stands at 270 VPs at the beginning. This, I guess, should pretty much help me avoid the major victory in 1944, is that reasonable? Will changing that affect anything else, like initiative change?
