Division Movement?

[bk6583]

Ok - been away for a few years but with the patches I'm back in it unfortunately with some rust to go with it. tried perusing the manual and couldn't a refernce to it. I thought there was a capability whereby you could click on a reachable hex (particularly along a road) and have the whole division start to move there, thereby avoiding the tedious task of moving 22 units individually. How is that done?
