Tab button

Hey Dev maybe just maybe can the TAB button work as cycle through melee units then archer, cav, siege, monks, fish boats, to warships. As in group them together when selecting a large army. Instead of single units place randomly in the bottom left corner and also if you can highlight them for quick select to tell a scout from a spear horse man that would be great. A button for quick removal from the group. (like ctrl click on the bottom icon remove that typeof unit from the group).
Can TC, keeps, tower, etc get a bell for quick garrisons?
Also can return back to work hot key on tower same as TC “C” instead of “D”
