Mutually beneficial friendship [Achievement] (Red Dead Redemption 2)

Hi all.
For not knowing you missed the case of the companion Chapter 4 (1-3 done)
But the game has already been passed and to go back I can't start the game from the beginning is also not an option (had completed more than 96%).

Is there any option to find the save game on Chapter 4 (but at the same time that this saves the business the satellite was covered in Chapter 1-3, that I was counted 4)

Or it is possible to do using the Save Editor {XB36Hazard}, where I never found such an item.

Thank you!
