'Straightening the Progress Line'

I hope I did not misunderstand your question. 

Pls make sure the option "Split in-progress tasks" is checked (note that, Project does not split/move fixed-duration type tasks). If you have all the "Move end/And move" options checked (as mentioned in your post), Project aligns the progress with the status date as soon as you input some progress on the tasks. 

Pls also see the following article:
