Avoid targeting enemy totems with TAB - possible?

As the title stats i would like to know if there is an option to only target players with tab and not totems.

Also when fighting hunters or warlocks, is there a way to quickly target those pets? like /target arena1 ... is there anything like /target arenapet1 or some other way to do it?

hope someone can help. thanks

Go to keybinds and bind tab to target nearest enemy player.
