Problem with keybinding

Hello, first of all i'm not sure if this thread it's well placed here at support, if not please forgive me.

I need help with a very specific problem. I've seted my keys this way: i cycle through units with TAB, i select all units in my control with SPACE BAR, and gives global orders with CTRL. The thing is i was playing meepo and suddenly a teammate went disconnected, and this ruined my game because anytime i cycled through the meepos with TAB or gave a global order, i selected the Disconnected hero too.
So my question is, if there's any way to exclude disconnected heroes from my global orders or TAB cycling?
Because i tried to re-set my keys and couldn't find any way.

I appreciate any help, and thanks in advance.

I also had this issue, I don't know a fix for this, but it's a good question, so if someone knows, please inform us!
