Question for Training SWs

I’ve been playing with Germans as my 3rd civ lately and am trying to figure if there is a hotkey for training SWs at the Mill the way you can use hotkeys to train to train vills at TC and units at barracks, etc. Do I really have to click the SW button each time?

Also, am I right I can’t command the SW out of the mill in advance (eg by selecting mill and then right clicking a hunt)? So I have to go back to the mill to command the SW manually every time the SW pops out?

Seems like I shoulda picked France for my third civ...
