Help -- 8 Unit Blink Spell

How would I go about creating a Blink type spell that would bring a small number of units along with the Hero? Iv'ed tryed to trigger this but can't figure out how to select the units to go along with the Hero because you cant select unit types when using Unit in Rect or Unit In Range of Unit.

There is a 'Units in Range Matching Condition'. It then depends on what units you want to be blinked. For example if you want all units owned by the player owning the hero, you'll have to use 'Owner of Picked Unit equal to Owner of Event Response - Casting unit'.
