Set default overwatch angle to maximum width

Could we get an option for overwatch cones to be set to maximum width as a default? I don’t know if it’s just me, but I’m much more likely to want to make overwatch as wide as possible than I am to narrow it and it feels like an unnecessary task to have to do that widening every time. you set overwatch. (I think the only time I’m going narrow overwatch is to avoid shooting my other soliders in the back of the head.)
