This is a pretty minor thing but its pretty annoying.
China can build a blockhouse that acts as a war academy for the most part, and if using the select all barrack type building hotkey, they are selected as a group, great.
However, if I set the Select Blockhouse hotkey and the Select War Academy hotkey to the same key, then they clash and I cant cycle through them.
Maybe there should be a “Select Barracks-type building” hotkey that select one of the buildings of the barracks type so you can cycle through them.
Same with stables, though the only difference for that is the Caravanserai.
