Please add an option to play only with bots. I want to appreciate the detail!

Please add an option so i can play only with bots. I want to look at the maps and appreciate the detail and missions, and everyone just runs through the missions. As a fan who wants to slow down and appreciate the details, an option to play only with bots so a single player can play at their own pace is something that is vitally needed.
I want to look at the majesty, but I cannot when its more of a race than a mission. I love the game otherwise, but it is very disappointing to miss everything due to the squad speed.
