Unpowered Wheels "Freeze" Option

I believe that Unpowered Wheels should have an option to "Freeze", just like cogs. To be honest, i have no idea why this isn't a thing yet, regardless, it would open up some interesting possibilities. Me, being an engine /car builder, always find myself needing to bodge things together using braces, which not only reduces engine power massively, it adds wheight to the whole machine. For me, at least, allowing for wheels to "Freeze" would make for some less complicated and cumbersome drivetrains, but i'm sure there are loads of other building areas whose builders would love this feature.
