Hotkey for upgrading units?

[rlplayer]

Hi, I been playing for a while and I feel an easy but convenient feature would be to assign upgrading units to two hotkeys, so I can just click on the unit and press a key to upgrade instead.

Right now I have to click on the unit and go down and click on the upgrade tab in order to upgrade, which is more work when I have around 20+ units variant in my army.

I'd love an "upgrade all" that upgrades all the units where there are enough horses and no choice to make as to path.
