i had this problem in aoe 4 too there are 3 ways to select ur buildings with hotkeys
to add them in a control group which is not the best since u have to do it every game
2 other ways is in hotkeys
1)to use the find (for example) town center :it puts the camera on top of the tc
2)find all town centers which is good since u dont have to look at ur tc everytime u wanna make a villager or when u are in battle and u wanna make some army u dont have to look away from the battle to make some army and again come back again and look at the army
the problem with the second option is that u cant use it like a control group what if i wanna center my camera on my tc but not all the time (like option 1 )
my solution is that so u make the option 2) just like control groups so when i click my hotkey 2 times my camera goes on the buidling
ive tried so much in aoe 4 to find another solution for this with different hotkey/ option and stuff but nothing worked
